+/**
+ * Recursively optimizes the syntax tree with a set of simple operations. This class currently
+ * optimizes:
+ * <ul>
+ * <li>String concatenation in var commands
+ * <li>Function calls to escaping functions
+ * </ul>
+ * <p>
+ * String add expressions in var commands are optimized by replacing something like:
+ *
+ * <pre>
+ * <cs? var:a + b ?>
+ * </pre>
+ * with:
+ *
+ * <pre>
+ * <cs? var:a ?><cs? var:b ?>
+ * </pre>
+ *
+ * This avoids having to construct the intermediate result {@code a + b} at runtime and reduces
+ * runtime heap allocations.
+ * <p>
+ * Functions call to escaping functions are optimized by replacing them with the equivalent escaping
+ * construct. This is faster because escapers are called with the strings themselves whereas general
+ * function calls require value objects to be created.
+ * <p>
+ * Expressions such as:
+ *
+ * <pre>
+ * <cs? var:html_escape(foo) ?>
+ * </pre>
+ * are turned into:
+ *
+ * <pre>
+ * <cs? escape:"html" ?>
+ * <cs? var:foo ?>
+ * <?cs /escape ?>
+ * </pre>
+ *
+ * It also optimizes sequences of escaped expressions into a single escaped sequence.
+ * <p>
+ * It is important to note that these optimizations cannot be done in isolation if we want to
+ * optimize compound expressions such as:
+ *
+ * <pre>
+ * <cs? html_escape(foo + bar) + baz ?>
+ * </pre>
+ * which is turned into:
+ *
+ * <pre>
+ * <cs? escape:"html" ?>
+ * <cs? var:foo ?>
+ * <cs? var:bar ?>
+ * <?cs /escape ?>
+ * <?cs var:baz ?>
+ * </pre>
+ *
+ * WARNING: This class isn't strictly just an optimization and its modification of the syntax tree
+ * actually improves JSilver's behavior, bringing it more in line with ClearSilver. Consider the
+ * sequence:
+ *
+ * <pre>
+ * <cs? escape:"html" ?>
+ * <cs? var:url_escape(foo) ?>
+ * <?cs /escape ?>
+ * </pre>
+ *
+ * In JSilver (without this optimizer being run) this would result in {@code foo} being escaped by
+ * both the html escaper and the url escaping function. However ClearSilver treats top-level escaper
+ * functions specially and {@code foo} is only escaped once by the url escaping function.
+ *
+ * The good news is that this optimization rewrites the above example to:
+ *
+ * <pre>
+ * <cs? escape:"html" ?>
+ * <cs? escape:"url" ?>
+ * <cs? var:foo ?>
+ * <?cs /escape ?>
+ * <?cs /escape ?>
+ * </pre>
+ * which fixes the problem because the new url escaper replaces the existing html escaper (rather
+ * than combining with it).
+ *
+ * The only fly in the ointment here is the {@code url_validate} function which is treated like an
+ * escaper by ClearSilver but which does not (currently) have an escaper associated with it. This
+ * means that:
+ *
+ * <pre>
+ * <cs? escape:"html" ?>
+ * <cs? var:url_validate(foo) ?>
+ * <?cs /escape ?>
+ * </pre>
+ * will not be rewritten by this class and will result in {@code foo} being escaped twice.

+ * tree.
+ *
+ * The Abstract Syntax Tree definition below is the only thing
+ * the Java application need to worry about. All previous definitions
+ * in this file are taken care of by the generated parser.
+ *
+ * Example input:
+ * Hello <?cs var:user.name ?>!
+ * <?cs if:user.age >= 90 ?>
+ * You're way old.
+ * <?cs elif:user.age >= 21 ?>
+ * You're about the right age.
+ * <?cs else ?>
+ * You're too young.
+ * <?cs /if ?>
+ * Seeya!
+ *
+ * Results in the tree:
+ * AMultipleCommand (start)
+ * ADataCommand (command)
+ * TData (data) "Hello "
+ * AVarCommand (command)
+ * AVariableExpression (expression)
+ * TWord "user.name" (name)
+ * ADataCommand (command)
+ * TData "!\n" (data)
+ * AIfCommand (command)
+ * AGteExpression (expression)
+ * AVariableExpression (left)
+ * TWord "user.age" (name)
+ * ADecimalExpresion (right)
+ * TDecNumber "90" (value)
+ * ADataCommand (block)
+ * TData (data) "\nYou're way old.\n"
+ * AGteCommand (otherwise)
+ * AEqExpression (expression)
+ * AVariableExpression (left)

+ * ADataCommand (otherwise)
+ * TData (data) "\nYou're too young.\n"
+ * ADataCommand (command)
+ * TData (data) "\nSeeya!\n"

+ *
+ * <p>When we receive a '/', we look at the previous non space character
+ * to figure out if it's the ending of a punctuator that can precede a
+ * regexp literal, in which case we assume the current '/' is part of a
+ * regular expression literal (or the opening of a javascript comment,
+ * but that part is dealt with in the state machine). The exceptions to
+ * this are unary operators, so we look back a second character to rule
+ * out '++' and '--'.
+ *
+ * <p> Although it is not straightforward to figure out if the binary
+ * operator is a postfix of the previous expression or a prefix of the
+ * regular expression, we rule out the later as it is an uncommon practice.
+ *
+ * <p>If we ruled out the previous token to be a valid regexp preceding
+ * punctuator, we extract the last identifier in the buffer and match
+ * against a list of keywords that are known to precede expressions in
+ * the grammar. If we get a match on any of these keywords, then we are
+ * opening a regular expression, if not, then we have a division operator.
+ *
+ * <p>Known cases that are accepted by the grammar but we handle
+ * differently, although I (falmeida) don't believe there is a
+ * legitimate usage for those:
+ * Division of a regular expression: var result = /test/ / 5;
+ * Prefix unary increment of a regular expression: var result = ++/test/;
+ * Division of an object literal: { a: 1 } /x/.exec('x');

+/**
+ * Holds a state table which is defined as the set of all
+ * recognized state transitions and the set of characters that
+ * trigger them.
+ *
+ * <p>The logic of what character causes what state transition is derived from
+ * a base definition written as a Python configuration file in the original
+ * C++ parser.
+ *
+ * <p>This class provides methods to initially build the state table and then
+ * methods at parsing time to determine the transitions to subsequent states.
+ *
+ * <p>Note on characters outside the extended ASCII range: Currently, all state
+ * transitions in the Python configuration file trigger only on extended
+ * ASCII characters, that is characters in the Unicode space of [U+0000 to
+ * U+00FF]. We use that property to design a more efficient state transition
+ * representation. When receiving characters outside that ASCII range, we
+ * simply apply the DEFAULT transition for the given state - as we do for any
+ * character that is not a hot character for that state. If no default
+ * transition exists, we switch to the Internal Error state.
+ *
+ * <p>Technical note: In Java, a {@code char} is a code unit and in some cases
+ * may not represent a complete Unicode code point. However, when that happens,
+ * the code units that follow for that code point are all in the surrogate area
+ * [U+D800 - U+DFFF] and hence outside of the ASCII range and will not trigger
+ * any incorrect state transitions.
+ *
+ * <p>This class is storage-inefficient but it is static at least
+ * and not generated for each Parser instance.
