Changes

Pathfinding and Decision Logic

• Added a function to check if a proposed square to move is either the edge or another snake on the board (including self)
• Added a very basic path finder that lines up on each axis

Other Changes

• Switched to APIv0 from APIv1 for compatibility with testing tools
• Refactored GameState and Decider class to simply take in all the request data. Any further parsing is done by the GameObject class

Further Changes

• Decide what piece of food to try and get.  #5 decide what piece of food to get
• Method to convert a board location to a direction #4 pick the next step in a better way
• What do we do when theres no food to go to? Moving randomly can trap ourselves, so we need some kind of "holding pattern"
• Better pathfinder? (Dijkstra? A*?)

[Harris-Ferguson]

It's probably about time to get this merged, I don't want this PR to bloat.

Features

• Added Testing Suite
• Small refactor of Decider and GameState to take in a single data object. Parsing of said object is left as a responsibility of the GameState object
• Added functions to probe the state of the board for hazards.
• Added the initial pathfinder. Simply lines up along the x axis and then the y axis.
