Got MatlabReader to encode .mat files as DataSet objects and started unit testing
MatlabReader now encodes .mat files with MLArray, MLDoubl, MLCell and MLChar as DataSet objects
Finish equality test. Checked times from dataset
Finished tests on MatlabReader.toString()
Added methode DataColumn.valueIsEmpty(int index)
Finished testing MatlabReader class
Updated documentation on MatlabReader test
Merge branch 'master' into Matlabreader
