Cake Cutting

Description

The year is 2035. Cake cutting is the last profession humans have left, everything else has been replaced by AI. Your job is to change that. Given a cake on STDIN and a series of cutting instructions, output the resulting cake, with slices separated.

You will be given a cake followed by a series of instructions in either the form x=… or y=…. The coordinates are 0 indexed for the spaces in between that row or column. For example, x=0 would indicate that you need to slice between the 1st and 2nd columns of the cake.
