/**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)]

  SideEffects       []
