Bugfix/115 analyse texts to cas returns results only after all data has been processed

[DavidHuebner]

Closes #115

• Analyse_texts_to_cas now returns results as soon as they are available
• Also fixed that client._analyse_text_xmi accepts a Path as input source; fixed signature
• Updated docstring with more detailed instructions on how to process documents in parallel
• Tested it against a HD (code not commited)
