void tunshift(Node ** list, Node *p)- "push" onto opposite end of temp stack
Node *pop(Node ** list)- Return the top symbol on the stack.

void push_namespace(Symbol *ns)- Push namespace onto the stack and set active namespace to top of stack.
Symbol *pop_namespace()- Pop namespace off the stack and set active namespace to top of stack. Leaves namespace symbol in symbol table.

AST *new_expr(int exprtype, AST *left, AST *right)- RT#48200: Not yet documented!!!
AST *new_op_expr(AST *left, int op, AST *right)- Specific type of expression (A b C) where b is an operator
AST *new_logical_expr(AST *left, int op, AST *right)- RT#48200: Not yet documented!!!
AST *new_if(AST *condition, AST *then_part, AST *else_part)- RT#48200: Not yet documented!!!

AST *new_for(AST *init, AST *condition, AST *iteration, AST *block)- RT#48200: Not yet documented!!!
Symbol *split(const char *pattern, const char *s)- Only using first char of pattern for now.
Symbol *lookup_symbol(const char *name)- Return first occurence of symbol in surrounding scopes.
Symbol *lookup_symbol_in_tab(SymbolTable *tab, const char *name)- RT#48200: Not yet documented!!!
Symbol *lookup_namespace(SymbolTable *tab, const char *name)- RT#48200: Not yet documented!!!

Symbol *store_symbol(SymbolTable *tab, Symbol *sym)- RT#48200: Not yet documented!!!
Symbol *store_method(SymbolTable *tab, const char *name, Type *type)- RT#48200: Not yet documented!!!
void declare_local(Symbol *s)- Method locals
void declare_field(Symbol *s)- Class fields
void dump_namespace(Symbol *ns)- RT#48200: Not yet documented!!!
void dump_symbol_table(SymbolTable *tab)- RT#48200: Not yet documented!!!
Symbol *check_id_redecl(SymbolTable *table, const char *name)- RT#48200: Not yet documented!!!
Symbol *check_id_decl(SymbolTable *table, const char *name)- RT#48200: Not yet documented!!!
int push_scope()- RT#48200: Not yet documented!!!
Symbol *pop_scope()- Pop current scope level and return a list of symbols if symbol table is passed.
void discard_scope()- Same as pop_scope except no list is built and returned. This is for cases where a list already existed, and each node was inserted into the symbol table, and we want to preserve that external list, so we can't scribble on the ->tnext pointer as it may reorder the list or invalidate it.
void push_primary_block(AST *p)- Don't laugh, this little array based stack is so I don't have to add a 3rd ->next pointer to the AST struct. It also means my design is wrong, will fix after adding brain expansion pack.
AST *pop_primary_block()- RT#48200: Not yet documented!!!
AST *get_cur_primary_block()- RT#48200: Not yet documented!!!
char *str_dup(const char *old)- RT#48200: Not yet documented!!!
char *str_cat(const char *s1, const char *s2)- RT#48200: Not yet documented!!!
