RunRouterCommand.py v1.2.0 (2014-03-17)

## RunRouterCommand.py v1.2.0 (2014-03-17) ##
* Replaced tab with four spaces.
* Application failed to fully execute because routerFile and commandFile
were
not defined.  Originally intended to update this code such that it would
read
these values from a config file but never finished that task.  Now
complete.
* Added error-checking around output file handling.
* Replaced ' with " to be consistent throughout the file.
* Updated `README.md` to match newest application design.
* Corrected problem where application would fail if logFileDirectory or
resultsFileDirectory in settings.cfg was blank.
* Added error-checking for resultsFileDirectory variable.
