This Makefile will be used as a way to start new projects with the same hierarchy. It will also be tightly coupled with the x testing framework for c (x_tfw4c). It has targets to setup the source, include, object, and tests directories using the `make dirs` command. There is some fun interesting things that I used to get the target to recompile when the header files are updated using the -MMD and -MP flags in gcc. These flags basically allow for the generation of dependencies from each source file that are exported and then included using the -include $(DEPENDENCIES) line at the bottem of the Makefile.
