/**
 * Overview:
 *
 * This is a simple top-down predictive parser. In a nutshell, there are two key
 * elements to a predictive parser. First, is the 'look ahead' symbol. This is simply 
 * the next token in the input stream. The other component is a stack of symbols. 
 *
 * Given the grammar, we can derive a look ahead table. This is just a 2D array, 
 * where one axis is the non-terminal on top of the stack and the other axis is 
 * the look ahead. Each entry in the array is the production to apply when the pair
 * of stack symbol & look ahead is encountered. If no production is listed at 
 * a given entry in the table, a parse error occurs if this combination
 * is seen.
 *
 * Since we want to drive the parsing from a couple of huge tables, we have to
 * save some information later on for processing (e.g. for code generation).
 * For this, we explicitly recreate the parse tree representing the derivation. 
 * We can then make several passes over the parse tree to perform all additional 
 * processing, and we can be sure the the parse is valid.
 *   
 * The stack is initialized by pushing the start symbol onto it. The look ahead
 * symbol is initially the first token in the program string. 
 *
 * If there is a non-terminal symbol on top of the stack, the look ahead table 
 * is consulted to find if a production exists for the top of the stack
 * and the look ahead.
 * 
 * When we find a matching production, we pop the non-terminal off the top of 
 * the stack (the LHS of the production), and push the tokens on the RHS of 
 * the production onto the stack. Note that we store a pointer to the parse_tree_node
 * containing the LHS token on the stack. This way, we can setup the children in 
 * the parse tree as we apply the production.
 *   
 * If there is a terminal symbol on top of the stack, we compare it with the
 * look ahead symbol. If they match, or we don't care about the value of the
 * terminal (e.g. we know its an integer, but don't necessairly care what 
 * integer), the terminal symbol is popped off the stack and the look ahead 
 * is advanced.
 *
 * There are a few special nasty cases of productions for which we make special 
 * cases. These aren't found in the production/look-ahead tables, but listed 
 * out explicitly.
 * 
 * After the parse tree has been constructed, we make several recusive passes 
 * over it to perform various tasks.
 *  
 * The first pass is made to clean up the state bindings.  This is done in 
 * parse_tree_fold_bindings(). The goal is to reduce the big mess of a parse tree
 * created by strings such as:
 * 
 *           result.color.secondary
 *
 * and roll them up into one token and fill out some information in a symbol table.
 * In this case, the token at the root of the derivation becomes BINDING_TOKEN,
 * and the token attribute is an index into the binding table where this state
 * is held.
 *
 * The next two passes go about associating variables with BINDING_TOKENs. This 
 * takes care of the cases like:
 *
 *           OUTPUT foo = result.color.secondary;
 *
 * by inserting the index in the binding table for result.color.secondary into 
 * the attr field in the identifier table where the 'foo' variable sits. 
 * The second such pass deals with setting up arrays of program parameters, 
 * while the first only deals with scalars.
 * 
 * We then examine all the information on variables and state that we have 
 * gathered, and layout which 'register' each variable or bit-of-state should use.
 *  
 *
 * Finally, we make a recursive pass of the parse tree and generate opcodes 
 * for Mesa to interpret while executing the program.
 * 
 * It should be noted that each input/stack token has two parts, an 'identifier' 
 * and an 'attribute'. The identifier tells what class the token is, e.g. INTEGER_TOKEN,
 * or NT_PROGRAM_SINGLE_ITEM_TOKEN. For some tokens, e.g. INTEGER_TOKEN, ID_TOKEN,
 * FLOAT_TOKEN, or BINDING_TOKEN, the attribute for the token is an index into a table
 * giving various properties about the token.
 *

/**
 * Here are all of the structs used to hold parse state and symbol
 * tables used.
 *
 * All strings which are not reserved words, floats, ints, or misc
 * puncuation (ie .) are considered to be [potential] identifiers.
 * When we encounter such a string while lex'ing, insert it into 
 * the id symbol table, shown below. 
 *
 * Sometime later, we'll initialize the variable types for identifiers
 * which really are variables. This gets shoved into the 'type' field.
 *
 * For variables, we'll need additional info (e.g. state it is bound to,
 * variable we're aliased to, etc). This is stored in the 'attr' field.
 * 	- For alias variables, the attr is the idx in the id table of
 * 	   the variable we are bound to.
 * 	- For other variables, we need a whole mess of info. This can be 
 * 	   found in the binding symbol table, below. In this case, the
 * 	   attr field is the idx into the binding table that describes us.
 * 	- For uninitialized ids, attr is -1.
 *
 * The data field holds the string of the id.
 *
 * len is the number of identifiers in the table.

/**
 * When we go to examine the parse tree to generate opcodes, things are not exactly pretty to deal with.
 * Parameters, constants, matricies, attribute bindings, and the like are represented by large numbers
 * of nodes.
 *
 * In order to keep the code generation code cleaner, we make a recursive pass over the parse tree and 'roll up' these deep
 * derivations of the attribs, and replace them with a single token, BINDING_TOKEN. The token attribute for 
 * BINDING_TOKEN is a index in the 'binding table' where all the relavant info on the chunk of state is stored, 
 * e.g its type.
 *
 * For example, the string 'vertex.color.secondary' is represented by 4 productions, and 4 nodes in the parse
 * tree. The token at the root of this derivation is NT_VTX_ATTRIB_BINDING_TOKEN. After this folding, 
 * the token at the root is BINDING_TOKEN, and s->binds[token_attr_at_the_root].type = ATTRIB_COLOR_SECONDARY.
 *
 * \param s    The parse state
 * \param ptn  The root parse tree node to start folding bindings
