I changed trick comm so that there is only one version built, not a slightly different version if you are in or out of a sim. While I was in the trick comm code, I removed all of the unnecessary system header file inclusions out of tc.h. I modified each of the source files to include the system files it requires. Some sim_services files were including tc.h and also had to be edited to add headers. I removed the stand-alone makefiles out of all of the trick_utils directories. Finally I modified the master makefile to exclude the trick_util directories comm, math, and units from being archived into libtrick.a. Each of those directories will create their own library and will be included when linking a Trick sim. refs #71
