This module provides functionality to catch errors and notify you if
something goes wrong, so if you do something heavily time consuming,
like training neural networks, searching primes, etc., you can walk
away and still know if an error occurs.

usage:
    from letmegetcoffee import lmgc

    # specify the type of exception you want to catch
    lmgc.EXCEPTIONS = IndexError  # or any other error(s); defaults to (Exception,)

    # specify the function to call after an exception
    lmgc.ON_EXCEPTION = lmgc.on_exception_beep  # starts to beep on exception

while 'lmgc.EXCEPTIONS' isn't really necessary to specify, 'lmgc.ON_EXCEPTION'
is really important to specify after import because it will default to 'print'
otherwise and just print out the exception-object.

At the moment the module only supports beeping on errors, but others like
email should come in the future.
