Detailed Description

Implementation for crash handling to create a stack trace when VG crashes. To use the crash handling system, call enable_crash_handling() early on in the program. When a crash occurs, you will recieve an error message with the stack trace. To get just a filename, you need to set the environment variable 'VG_FULL_TRACEBACK=0'.
