questions Testing

*Added testing for question classes
*Added close button to return
*Changed filetype of sample from rtf. to xml
*Commented test functions in MazeGUI and RoadBlock
*Added string close to the strings.xml
*Assigned the id "question" to the question TextView in
activity_road_block.xml

Notes:
*The question parser isn't currently working. This problem is likely due
to the file path. The question parser used in MazeGUI.java -> public
void roadBlockEnc (View view).
