Allow multiple entities

[mafm]

Entities should be hierarchical (like accounts) and transactions should have to balance for each entity mentioned in the transaction.

Should probably show entities like this:

2009-02-27 'Owner' lent $100 to 'FamilyBusines'. Business owes that money to 'Owner'
Owner/Assets:Cash -$100
Owner/Assets:Receivable:FamilyBusiness $100
FamilyBusiness/Assets:Cash $100
FamilyBusiness/Liabilities:Owner$100

You could then drill down to entities to work out what their p/l or balance sheet looked like. Several entities could keep assets in the same account, or more likely you might have sub-entities for different activities within an entity, sharing an account, but you could always break the balance in an account up between the different entities using it.
