Made changes to Graph.h and main() in order to compile.  Graph now works for int
Added a constructor to Edge. Implemented minimum spanning tree function for Graph. Added more content to main()
Worked with remove() a bit, still issues with findEdge()
Fixed findEdge(), was returning an iterator to a local variable which was causing dangling pointer. Fixed formatting in main()
Added more stuff to main(), still outstanding issues with BFSSearch() minspantree()
