Detailed Description

Replaces some default lex functions.

The replacement functions all it to work on a string named parse_string (size parse_length). ALL lex/yacc related variables are in global namespace, only parseQuery is in the usual ibis namespace.

Note:

The only function that should be used elsewhere is parseQuery

    ibis::qExpr* ibis::parseQuery(const char* str)
