+Steps to running interpreter:
+
+1.Make sure DYLD_LIBRARY_PATH if using this on a Mac contains the directory of the qextserial libraries. This can be done in the run settings in Qt
+2.Set the Interpreter project to depend on src.pro (in Common/JrKerr/src/ but src.pro MUST be opened with Interpreter.pro to do this)
+3.Delete text in “Command” in the “Generate GUI” build step and add in “uic”
+4.Compile project
+5.Make sure the executable is set to active in Qt settings (and make sure that Qt has the right executable set)
