New parser system is needed

[MathieuAA]

Each editor differs from the others and including each editor's changes in one file (xmiparser) is difficult and ugly. The news system will have different files (one file for each editor) so that if a change is needed, a new file would be created instead of modifying the same ol' file.

This new system will change only the parsing part of JHipster-UML, and we'll try not to make it as a breaking change (i.e. 1.0.0, but more of a 0.N+1.0).

Closed as the "parserchange" branch will very soon be merged.
