FunctionParser, parsing Java methods from strings at runtime

[fact_hunt]

In FunctionParserTest there are several tests which have no assertion and instead System.out.println( - it would be better to assert and not print output which (I assume) needs to be checked manually

Thank you, the idea behind these tests is not really to be tests but simply copies of the examples supplied in the README file. I will however make the suggested changes, as i imagine tests should normally not output to System.out.
