Tool that takes a maze as a CSV file and outputs a path as a CSV file.
W - Symbol for wall (can not create path through walls).
S - Symbol for start point.
E - Symbol for end point.
P - Symbol for path. If a path needs to be created through a weighted cell, it will be concatenated at the end of the cell; for example, a path through a cell with weight of "3" would appear "3P" instead of "P".

Blank cells have a weight of 1 by default.
Weighted cells are denoted by integer values, a cell with the integer 2 is worth 2x more than a blank cell.
