This is a basic exception. All the other AVDesk family exceptions classes are inhereted from it.

- lib_function — dwavdapi library function name on which execution error has occured.
- lib_errno — Error code returned by dwavdapi library.
- lib_function_args — Arguments passed to dwavdapi library function.
