#5 Fix Project Grader compilation errors

[N Napier]

The MathFunction.java file generated did not compile.

(1) First error was related to comments. The /** was missing a closing **/

/**
* "This will test the MathFunctions class which contains add, multiply, etc. Use for the Spring 2010 section of ITEC 2120"
* Input .CSV: SampleInputFileProfs.txt
**/

(2) When I fixed that error in the source file, I received another set of errors:

[javac] C:\Documents and Settings\nnapier\workspace\codeturtle2\build.xml:197: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds

Problem # 2 above was resolved by a correction of the *.txt file. Please ignore.

Additional issues:
(3) When calling the register method, the first argument to the method should be an integer instead of a double:

register(5, "Add one number"); // NPN 5.0 to 5

(4) When calling the invokeMethod, should cast the return code to Integer instead of int

(Integer) invokeMethod(sumMethod, mathfunctions, new int[]{5}); // NPN int to Integer
