Title: Issue-258 Generate warning for non-used private attributes and methods

Added analysis of usage of private methods and attributes. Warning message is generated if attribute/method declared but never used.

AssertionVistor: added configurable option for enabling/disabling warnings.
TypechekerBuilder: added option for enabling/disabling warnings instead of method override.
