Based on the Array.py and SimpleSorting.py visualizations,
implement a new VisualizationApp that displays an inital 10-element array
along with New, Random Fill, and Delete Rightmost operations on the array.
The New operation takes an argument for the number of cells in the array
and creates empty frames for the array values. Random fill puts values
in all the array cells, regardless of their current values. The values
are ordered from lowest to highest. Delete Rightmost should either be
disabled or report an error when the array is empty.
The other operations on the array are in separate issues.
