Library-specific exception

[ZdenekM]

Right now, the handle_response raises Exception:

fanucpy/src/fanucpy/Robot.py

Line 61 in 27a70d1

raise Exception(msg)

which is probably not a good practice. I propose to define at least one library-specific exception and optionally other derived exceptions... Something like this:

class FanucPyException(Exception):
    pass

class CommException(FanucPyException)
    pass

Which will allow me (in the application code) to catch just the specific exception raised by the library, instead of the generic one.

Thanks for your consideration.
