Refs #31

Implementation Note:
I basically copied the logic of objectMap to implement predicateMap.

Hi,

The change is not obvious because the whole file appears to have been changed. Could you please commit in a way that clearly shows changes in the files Parser.java and PredicateObjectMap.java?

Thank you for your contributions.

Best,
Nikolaos

Yes you are absolutely right.
The issue was that there seem to be two different types of line separators in the project. Parser.java and PredicateObjectMap.java use CRLF while the rest of the files seem to use LF. I fiddled around a bit and setting git config core.autocrlf false finally did the trick.
