Delegate
Don't provide the aggregate

It's the aggregate being currently modified.
Rename method to convey meaning better
less delegation... fixup
Start of support for recurrent allocations on advanced allocation

The information needed is provided in the AllocationInputs, but the
Rows don't use it yet.
Use an enum instead of int attribute

It conveys better the meaning when the constructor is being called.
Constraint for total effort no longer exists

Removing unnecessary code.
Remove no used field
Provide the recurrent allocations too
Support assignation of efforts to recurrent allocations

The assigned effort of a changed cell is distributed among the
recurrences that fall within that cell. The load proportion of each
allocation is kept.
