Exceptions are not logged completely

[ftc]

The current idea is to first log the entry and exit of each callin. If an entry is seen but not an exit this implies that an exception was thrown however we don't know what exception without adding more instrumentation. This is a todo to add that when needed.

Exception logging to add:

• Log exception type
• String primitives up to a given length
• method name and class_name for the method that it was logged in
• stack trace from exception
  • should this be split into individual components?
