Adding graphical components to the DocumentAnalyzer to handle the input file format (xcas, xmi, textDocument)

In the uimaj-tools package, the DocumentAnalyzer class [1] does not offer the way to graphically set up the input file format (xcas, xmi, textDocument) while it uses the FileSystemCollectionReader class [2] which offers its possibility.

We propose to add two graphical components: one to set up the input file format (xcas, xmi, textDocument) and the other to indicate if the execution must fails if an encountered type is unknown (when parsing xmi files).
