Christopher Lam b2fcfbd3c6 Bug 797326 - Enhancement: budget's Estimate tool should ignore Closing Entries
Addendum to 8b8c957ed -- if budgeted amounts exclude closing entries,
actual amounts should also exclude closing entries.

Amend documentation, modify budget test to add a closing entry which
will be ignored.

/** @file gnc-budget.h
* @brief GnuCash Budgets
*
* Design decisions:
*
* - The budget values that the user enters (and that are stored) for
* each account are inclusive of any sub-accounts.
*
* - Reason: This allows the user to budget an amount for a
* "parent" account, while tracking (e.g.) expenses with more
* detail in sub-accounts.
*
* - Implication: when reporting budgeted values for parent
* accounts, just show the stored value, not a sum.
*
* - Budget values are always in the account's commodity.
*
*
*
* Accounts with sub-accounts can have a value budgeted. For those
* accounts,
*
* Option 1: when setting or getting budgeted values, the value is
* *always* exclusive of sub-account values. Pro: consistent
* values in all contexts. Con: no summary behavior.
*
* Option 2: make setting only for account proper, but always
* report summaries. Con: value can change as soon as it is
* entered; forces entry from bottom-up.
*
* * Option 3: value is always *inclusive* of sub-accounts, although
* potentially in a different commodity. Pro: allows top-down
* entry; no auto value update. Con: ? [ This option was selected. ]
