###Statement of work:

You're given the task of writing a simple console version of a drawing program. At this time, the functionality of the program is quite limited but this might change in the future. In a nutshell, the program should work as follows:

1. Create a new canvas
2. Start drawing on the canvas by issuing various commands
3. Quit

Command	Description
C w h	Should create a new canvas of width w and height h.
L x1 y1 x2 y2	Should create a new line from (x1,y1) to (x2,y2). Lines will be drawn using the 'x' character.
R x1 y1 x2 y2	Should create a new rectangle, whose upper left corner is (x1,y1) and lower right corner is (x2,y2). Horizontal and vertical lines will be drawn using the 'x' character.
B x y c	Should fill the entire area connected to (x,y) with "colour" c. The behaviour of this is the same as that of the "bucket fill" tool in paint programs.
Q	Should quit the program.

Sample I/O

Below is a sample run of the program. User input is prefixed with "Input command:"
