Copy edit to tutorial text and font size change for n-back counter text.
Merge branch 'develop'
Added a colorSet and shapeSet variable. Defaulted to a new colorSet and a new shapeset. Added some logic so you can skip the tutorial by selecting n value that's greater than 1.
Added a fade between drawObject calls and added a global variable for object display time.
Renamed my addGenericMatch5000 function to createMatch and renamed addMatches function to insertMatches.
