""" Power Class
Properties:
- **abbrev** - Contains the abbrev of the power (i.e. the first letter of the power name) (e.g. 'F' for FRANCE)
- **adjust** - List of pending adjustment orders
(e.g. ['A PAR B', 'A PAR R MAR', 'A MAR D', 'WAIVE'])
- **centers** - Contains the list of supply centers currently controlled by the power ['MOS', 'SEV', 'STP']
- **civil_disorder** - Bool flag to indicate that the power has been put in CIVIL_DISORDER (e.g. True or False)
- **controller** - Sorted dictionary mapping timestamp to controller (either dummy or a user ID) who takes
control of power at this timestamp.
- **game** - Contains a reference to the game object
- **goner** - Boolean to indicate that this power doesn't control any SCs any more (e.g. True or False)
- **homes** - Contains a list of homes supply centers (where you can build)
e.g. ['PAR', 'MAR', ... ] or None if empty
- **influence** - Contains a list of locations influenced by this power
Note: To influence a location, the power must have visited it last.
e.g ['PAR', 'MAR', ... ]
- **name** - Contains the name of the power (e.g. 'FRANCE')
- **orders** - Contains a dictionary of units and their orders.
For NO_CHECK games, unit is 'ORDER 1', 'ORDER 2', ...
- e.g. {'A PAR': '- MAR' } or {'ORDER 1': 'A PAR - MAR', 'ORDER 2': '...', ... }
- Can also be {'REORDER 1': 'A PAR - MAR', 'INVALID 1': 'A PAR - MAR', ... } after validation
- **retreats** - Contains the list of units that need to retreat with their possible retreat locations
(e.g. {'A PAR': ['MAR', 'BER']})
- **role** - Power type (observer, omniscient, player or server power).
Either the power name (for a player power) or a value in diplomacy.utils.strings.ALL_ROLE_TYPES
- **tokens** - Only for server power: set of tokens of current power controlled (if not None).
- **units** - Contains the list of units (e.g. ['A PAR', 'A MAR', ...]
- **vote** - Only for omniscient, player and server power: power vote ('yes', 'no' or 'neutral').
