====== Important kuimaze2 datatypes ======

===== State =====
Class ''State'' encapsulates a position in a maze, i.e. a row ''r'' and a column ''c''. You can create a ''State'' like this:

<code python>
>>> from kuimaze2 import State
>>> state = State(1, 2)
>>> state
State(r=1, c=2)
</code>

You can easilly see what position the state represents. But in your algorithms you will almost never need to create a ''State'' instance yourself. (But you may need to create a ''State'' instance in your testing code.)

===== Action =====
Class ''Action'' is an ''Enum'' and represents 4 actions available for your agents to choose from:

<code python>
>>> from kuimaze2 import Action
>>> Action
<enum 'Action'>
>>> actions = list(Action)
>>> actions
[<Action.UP: 0>, <Action.RIGHT: 1>, <Action.DOWN: 2>, <Action.LEFT: 3>]
>>> actions[0] == Action.UP
True
