minor tweaks in testQuestion.jsp to improve aesthetics
utils.js is changed (sendToEvaluate() and showResults()) to work with field names XML data format

math1206.nb now generates problemData xml strings with tests
math1206.m is an autogenerated math-package file, included just in case

CheckAnswers class now processes the POST request properly , gathers dependencies, executes the test and returns the raw XML data to the sender
ProblemData had some method names tweaked, it now adds and returns optionStrings intelligently
ProblemPuller processes XML data returned from problem generators
Added a few files to complete the previous commit
