* Simple if statement processor
*
* This module can be used to evaluate string representations of C language
* if constructs. It accepts the following grammar:
*
* EXPRESSION := VALUE
* | VALUE BINOP EXPRESSION
*
* VALUE := '(' EXPRESSION ')'
* | '!' VALUE
* | '-' VALUE
* | 'defined' '(' variable ')'
* | variable
* | number
*
* BINOP := '*' | '/' | '%'
* | '+' | '-'
* | '<<' | '>>'
* | '<' | '>' | '<=' | '>='
* | '==' | '!='
* | '&' | '|'
* | '&&' | '||'
*
* The normal C order of precidence is supported.
*
*
* External Entry Points:
*
* ParseIfExpression parse a string for #if
