DiagramMaker is a proof-of-concept program and has several draw backs.
The names of example files are currently hard-coded thus limiting the number of patterns that can be presented..
Some other techniques should be explored in addition to reflection and introspection framework to analyze example files. One draw back of the current approach is addition of outgoing messages to an IC Card that are not really used.
I believe that all of those limitations can be overcome, if more resource are allocated to the development of these types of prejects.
