Added a help feature.  Alt+C+Clicking an element will display that element's function. The user is now able to add groups to existing families. When a parameter is removed from a family, all of the parameters that belong to the same group are removed with it. Same goes for removing parameters from an existing family. Also, if the user is about to remove the last group from a family, it deletes the whole family. Some more strenuous tests are still needed.  We need to try to add a full featured product with ports and all.
