Convert string map output into numpy array or numeric matrix

[chm10]

Is difficult to operate using only a big string with \n characters. So I will convert string into numpy array.

[0, 0, 0, 0, 0, ...]
[0, 0, 0, 0, 0, ...]
[0, 0, 0, 0, 0, ...]
...

Some settings to issue #3

• Map size as 31 x 28
• Considering | as wall == 0 and . as path == 1
  *0 == wall , 1 == path, 2 == startpoint, 3 == goal , 4 == block
