Use the Shift-Reduce Parser

[KaisongHuang]

I haven't figured out which is the default model that corenlp uses to parse sentences. I tried to explicitly call the following method to use englishSR which corenlp says has better performance:

// use faster shift reduce parser
props.setProperty("parse.model", "edu/stanford/nlp/models/srparser/englishSR.ser.gz");

And I got the following error:

edu.stanford.nlp.io.RuntimeIOException: java.io.IOException: Unable to open "edu/stanford/nlp/models/srparser/englishSR.ser.gz" as class path, filename or URL

I just commented the above line for now and maybe we can work on it later.
