diff include/AGC.h @ 503:83cd5bbf2a3e carfac_cpp

* Added class Ear, and moved the CARFAC members AGC CAR IHC into Ear. CARFAC now holds an array of Ear. TBD what is best.

* Moved the files around, and introduced a makefile that builds unittests using GTest. (Note, GTest path is configured in makefile atm.).
- two moronic tests implemented. :)
