Getting ready to add some utilities
Add utilities to enable/disable pwm
Adding find utility
laying out how pwms will be added
flushing out pwm functionality
Working on getting/setting values in the pwm.
Document output parameters
Wrote test and fixed shitty code
Switch to requireing paths so the pwm is more independent
Added code for setting, needs tests
Switch to using freopen, add tests for basic fileio
Adding some more tests
rename pwm_io test to file_io test, get ready to create pwm_control tests
switch to r+ from w+ to not overwrite
when reopening use w+ to truncate
forgot what w+x actually does, added tests to see if we can actually write to the file
Starting to refactor to using a test macro instead of an assert, adding more tests
Make a travis .yml
make apt-get quiet
Switch back to exiting after a test failure
