/**
* A jMusic tool which displays a score as a simple
* 'piano roll' display in a window.
* The tool displays a jMusic class as a simple piano roll view. To use it write:
* new ViewScore(scoreName);
* Where scoreName is the jMusic Score object.
* Alternately:
* new ViewScore(scoreName, xpos, ypos);
* Where xpos and ypos are intergers specifying the topleft position of the window.
* This is useful if you want to use ViewScore in conjunction with some other GUI interface
* which is already positioned in the top left corner of the screen.
