Added missing host_receiver.h file

Extensions to host receiver

Also moved the functionality of each command into it's own method.

pyenergy.so is built into .host/.libs.
Can be built with python 2 or 3.
--with-python option added to configure script, which should point to the python
binary that should be used to build the module.

A DataProcessor now only lasts as long as results are being recorded.
An alternate output file an be specified with the start command.

Added closeOutput and openOutput to the DataProcessor to allow results files
to be opened and closed on demand.
