Called to allow the player to propose a deal.
You return a DealProposal object.
If you do not want to make a deal, return None.
If you want to make a deal, you provide this information:
- The player number of the player you are proposing the deal to
- A list of properties offered
- A list of properties wanted
- Maximum cash offered as part of the deal
- Minimum cash wanted as part of the deal.
Properties offered and properties wanted are passed as lists of
Property objects.
If you offer money as part of the deal, set the cash wanted to zero
and vice versa.
Note that the cash limits will not be shown to the proposed-to player.
When the deal is offered to them, they set their own limits for accepting
the deal without seeing your limits. If the limits are acceptable to both
players, the deal will be done at the halfway point.
For example, Player1 proposes:
Propose to: Player2
Properties offered: Mayfair
Properties wanted: (none)
Maximum cash offered: 0
Minimum cash wanted: 500
Player2 accepts with these limits:
Maximum cash offered: 1000
Minimum cash wanted: 0
The deal will be done with Player2 receiving Mayfair and paying £750
to Player1.
The only 'negotiation' is in the managing of cash along with the deal
as discussed above. There is no negotiation about which properties are
part of the deal. If a deal is rejected because it does not contain the
right properties, another deal can be made at another time with different
lists of properties.
Example construction and return of a DealProposal object:
return DealProposal(
propose_to_player_number=2,
properties_offered=[vine_street, bow_street],
properties_wanted=[park_lane],
maximum_cash_offered=200)

def propose_deal(self, game_state, player):
'''
Called to allow the player to propose a deal.
You return a DealProposal object.
If you do not want to make a deal, return None.
If you want to make a deal, you provide this information:
- The player number of the player you are proposing the deal to
- A list of properties offered
- A list of properties wanted
- Maximum cash offered as part of the deal
- Minimum cash wanted as part of the deal.
Properties offered and properties wanted are passed as lists of
Property objects.
If you offer money as part of the deal, set the cash wanted to zero
and vice versa.
Note that the cash limits will not be shown to the proposed-to player.
When the deal is offered to them, they set their own limits for accepting
the deal without seeing your limits. If the limits are acceptable to both
players, the deal will be done at the halfway point.
For example, Player1 proposes:
Propose to: Player2
Properties offered: Mayfair
Properties wanted: (none)
Maximum cash offered: 0
Minimum cash wanted: 500
Player2 accepts with these limits:
Maximum cash offered: 1000
Minimum cash wanted: 0
The deal will be done with Player2 receiving Mayfair and paying £750
to Player1.
The only 'negotiation' is in the managing of cash along with the deal
as discussed above. There is no negotiation about which properties are
part of the deal. If a deal is rejected because it does not contain the
right properties, another deal can be made at another time with different
lists of properties.
Example construction and return of a DealProposal object:
return DealProposal(
propose_to_player_number=2,
properties_offered=[vine_street, bow_street],
properties_wanted=[park_lane],
maximum_cash_offered=200)
The default is for no deal to be proposed.

def build_houses(self, game_state, player):
'''
Called near the start of the player's turn to give the option of building houses.
Return a list of tuples indicating which properties you want to build houses
on and how many houses to build on each. For example:
[(park_lane, 3), (mayfair, 4)]
The properties should be Property objects.
Return an empty list if you do not want to build.
Notes:
- You must own a whole set of unmortgaged properties before you can
build houses on it.
- You can build on multiple sets in one turn. Just specify all the streets
and houses you want to build.
- Build five houses on a property to have a "hotel".
- You specify the _additional_ houses you will be building, not the
total after building. For example, if Park Lane already has 3 houses
and you specify (park_lane, 2) you will end up with 5
houses (ie, a hotel).
- Sets must end up with 'balanced' housing. No square in a set can
have more than one more house than any other. If you request an
unbalanced build, the whole transaction will be rolled back, even
if it includes balanced building on other sets as well.
- If you do not have (or cannot raise) enough money to build all the
houses specified, the whole transaction will be rolled back. Between
this function call and money being taken, you will have an opportunity
to mortgage properties or make deals.
The default behaviour is not to build.
