Spiked drawing a line to mouse click location
Spiked mouse dragging code
Cleaned up client tests

Simulated click event
Trying to adjust for border width--not working yet
Cleaned up mouse test code
Draws line segments in response to clicks
Started on supporting multiple line segments
Simplified paper path assertions
Created paperPaths() function for easier assertions
Factored out paperPaths() and got tests to pass; doesn't work in all cases yet
