/**Function********************************************************************
Synopsis [The type core violation handler.]
Description [The violation handler is implemented as
a virtual method, which is invoked by the checker when an expression
being checked violates the type system.
See the violation handler TypeCheckingViolationHandler_ptr
for more explanations.
The below function is the default violation handler, and a
user can potentially define its own violation handler, by deriving
a new class from this class and by overriding this virtual method.
This violation handler outputs an error and warning message to
nusmv_stderr. A warning is output if the detected violation is
TC_VIOLATION_TYPE_BACK_COMP and the system variable
"type_checking_backward_compatibility" is true. Also the
TC_VIOLATION_TYPE_WARNING violation outputs a warning. Only in this
case the false value is returned, indicating that this is NOT an
error. Otherwise the true value is returned, indicating that this is
an error.
Also, if the system variable "type_check_warning_on" is false,
warning messages are not output.
NB: if the expression is checked in some context (context is not null) then
before providing the expression to this function the expression should be
wrapped into context, i.e. with find_node(CONEXT, context, expr)]
