[Mathlib-develop] Minor changes

[Stefan M. <st...@he...>]

Hi,

in Parser.java I changed a System.out.println to ErrorLogger.debugLIne

In UserFunctin.java I remove two null pointer exceptions when working 
with functions which don't have left nor right handside arguments.

In the testsuite I commented the use of assert(), because java 1.4
doesn't like it.

Kind regards,
   Stefan.
