Updated ScoringUtils.py to use cssefwebfront.models.Score rather than its own Score object
Updated OpenPort.py to work with the pluggin environment. This has been tested and works.
Updated documentation! Better description of how to use the pluggin testing environment.
Cleaned up the way the score object returned by the pluggin is handled. Object fields are fully filled and then saved in the run_loop function rather than the log function. The log function does only logging (to stdout) as expected.
