Multiplexing interface for the CMU Pocket Sphinx engine

"""
Timer manager for the CMU Pocket Sphinx engine.
This class allows running timer functions if the engine is currently
processing audio via one of three engine processing methods:
- :meth:`process_buffer`
- :meth:`process_wave_file`
- :meth:`recognise_forever`
Timer functions will run whether or not recognition is paused
(i.e. in sleep mode).
**Note**: long-running timers will block dragonfly from processing what
was said, so be careful with how you use them! Audio frames will not
normally be dropped because of timers, long-running or otherwise.
Normal threads can be used instead of timers if desirable. This is
because the main recognition loop is done in Python rather than in C/C++
code, so there are no unusual multi-threading limitations.
