added google mock to libs
started over with gmock
integrated gmock with build
minor cleanups
not working test using google mocks ... might scrape gmock, too much of a hassle to set up
gyroscope test is now a basic gmock example test
added debug printer, tried to get test_gyro to work, fixed all compiler errors, but got some linker errors now
got gmock in place, src/test_gyro.cppNO is an example of how to use gmock, gyro test is completely broken, therefore not in here, snprintf doesn't work, therefore not using it for now
