+ * 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 ':'	EXPRESSION
+ * 
+ *     VALUE		:=	'('  EXPRESSION  ')'
+ * 			 |	'!'  VALUE
+ * 			 |	'-'  VALUE
+ *			 |	'~'  VALUE
+ * 			 |	'defined'  '('  variable  ')'
+ * 			 |	variable
+ * 			 |	number
+ * 
+ *     BINOP		:=	'*'	|  '/'	|  '%'
+ * 			 |	'+'	|  '-'
+ * 			 |	'<<'	|  '>>'
+ * 			 |	'<'	|  '>'	|  '<='  |  '>='
+ * 			 |	'=='	|  '!='
+ * 			 |	'&'	|  '^'  |  '|'
+ * 			 |	'&&'	|  '||'
+ * 
+ * The normal C order of precedence is supported.
+ * 
+ * 
+ * External Entry Points:
+ * 
+ *     ParseIfExpression		parse a string for #if
