*** The Problem ***
__Description__
You're given the task of writing a simple console version of a drawing program.
At this time, the functionality of the program is quire 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). Currently only
horizontal or vertical lines are supported. Horizontal and vertical 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 enter command:
enter command: C 20 4
