Changed the on time for a given bin to be set from the observation being filled into the cube rather than the cube itself.

Updated writing information to log file in order to prevent messy log file messages. This doesnt appear to impact the computation time.

Optimized computation intensive parts of ctmodel to reduce computation time.
Implemented openmp parallelization of ctmodel to reduce computation time.

The working log file pointer was not forwarded to ctobssim::set_mc_id_names() and consequently the standard log file pointer was used, which occasionally lead to the exception during the Python unit test. Now the log file pointer is forwarded properly.

…kymap and method that returns model container

…servation container through the obs() method.
