FileSystemCollectionReader doesn't set lastSegment correctly

FileSystemCollectionReader only sets lastSegment=true (in the SourceDocumentInformation) on the last document. Given that it loads individual documents, not segments of a document, this should be "true" for each CAS that it generates.

This is a problem when later using a CAS multiplier to segment the CAS. It should be possible to check whether the CAS is a complete document or a segment by testing for "offsetInSource==0 && lastSegment==true".

in org.apache.uima.examples.cpe.FileSystemCollectionReader:166

srcDocInfo.setLastSegment(mCurrentIndex == mFiles.size());

should be:

srcDocInfo.setLastSegment(true);
