Create flow diagrams displaying possible actions

[Dev-Laurin]

Create some diagrams showing what a player can do and what ends their turn.

For example:

A pawn can move if not trapped by enemy units, has enough movement for the land, and is not blocked by friendly or 3rd party units.

A pawn can use a tool/weapon within that weapons range. A bow will have 2 range vs a sword's 1 range.

A pawn can start with either movement or a tool but cannot use a tool then move. A pawn must move first then use a tool then the turn ends.

Created a flow markdown file to show what a pawn can do.
