Detailed Description

Constructs a Stack hint for the given symbol.

The class knows how to construct the stack hint message based on traversing the CallExpr associated with the call and checking if the given symbol is returned or is one of the arguments. The hint can be customized by redefining 'getMessageForX()' methods.
