Fixed DisplaySetting to return null if no setting is found, rather than
raise NullPointerException
Implemented basic drawing of numbers on the y axis. Tested. Still need
to implement drawing of numbers of x, and auto sizing of the numbers
based on chartDimensions.height
Changed example range, removed unneeded print statements
Fixed example to not add points on whenever paintComponent is called.
Moved functionality to actionPerformed
Small bug fix: forgot to increment to i in actionPerformed
Implemented basic scaling functionality. WARNING: horribly inefficient, methods need to be moved out of the repainting context.
