Adding a compare feature

[sid-am-ahd935]

Currently only 1 algorithm can be used at once.

• Solution 1: Create a multi select type of feature which will show split screen on the root window for each algorithm in play.
• Solution 2: Creating a new button feature which spawns a new window of the selected algorithm independent of the root window.

Note that multi threading / multiprocessing would be required as well as generating a lock function such that an algorithm is not selected twice.
