Minor fix to printCrudeAndAdjustedModel
printCrudeAndAdjustedModel needed a minor fix for the labels as I haven't used the levels() for getting the factor levels since some may be empty
Changes for 0.5.7.1
-------------------
* Fixed rownames in printCrudeAndAdjusted
* Changed printCrudeAndAdjusted to return a matrix subclass instead of immediately printing
* Ran through som Pkg-check and hopefully cleared out some bugs
