/**
* The fundamental data construct of this class is a 'grid'. It is organized as follows:
*
* A 'Row' is a row of money values, each column is a month. The first month corresponds to
* m_beginDate.
*
* A 'Row Pair' is two rows of money values. Each column is the SAME month. One row is the
* 'actual' values for the period, the other row is the 'budgetted' values for the same
* period. For ease of implementation, a Row Pair is implemented as a Row which contains
* another Row. The inherited Row is the 'actual', the contained row is the 'Budget'.
*
* An 'Inner Group' contains a rows for each subordinate account within a single top-level
* account. It also contains a mapping from the account descriptor for the subordinate account
* to its row data. So if we have an Expense account called "Computers", with sub-accounts called
* "Hardware", "Software", and "Peripherals", there will be one Inner Group for "Computers"
* which contains three Rows.
*
* An 'Outer Group' contains Inner Row Groups for all the top-level accounts in a given
* account class. Account classes are Expense, Income, Asset, Liability. In the case above,
* the "Computers" Inner Group is contained within the "Expense" Outer Group.
*
* A 'Grid' is the set of all Outer Groups contained in this report.
