WebStyler: The IfStack object

The IfStack object represents the state of all conditional expansions inside a template. It is basically a container class for Condition objects. Methods:

• If_Stack_New() is the constructor, returning an empty IfStack.
• If_Stack_Else() is called when an %else; construct is seen
• If_Stack_End() is called upon detecting the end of a conditional (%endif;).
• If_Stack_Is_Skipping() is a predicate use to test whether we are currently expanding text, or skipping it.
• If_Stack_Start() is called upon detecting the start of a conditional.
