starting Load test
Added src/os to hold the network operating system.

Development has begun. The OS is to coordinate all actions between
the NMUs. As permissions are created and destroyed, the OS must
keep the NMUs up to date. So far, the add* functions have been
created, however, they are not yet tested.
Created rand/Random, Still working on OS
more work in OS_TEST
working on Log regexs
Added RE2 library for the Logger

The logging system's list can now handle regular expressions.
TODO: use G++ 4.9's std::regex when available
Removed unneeded src/load
More work on OS_TEST
Created the main program

The main program is now the finished OperatingSystem_TEST.singleHwNmu.
A few changes in the logging scheme to handle the RE2 library better.
Created rand/RandomSet to aid random number set distribution.
