annotate makefile @ 578:86601f76f47a carfac_cpp

seemingly mingw likes tabs for makefiles ...?
+ some restructure and automatic execution of unittests after build...

# How to use:
# Add your cpp code to the list in UNITS.
#
# Unit test:
# If you want to add a test build target for that cpp file ONLY, please see 
# example "AGC_unittest". (no need to add explicit build rule)
#
# If you intend to test a class including instanciated members, you need to 
# make a explicit rule to link properly. See example "CARFAC_unittest".
