The .value attribute of a StatCell may be in one of three states:
If this is a suffix cell in a KeyRow,
the .value attribute is the column
label as a string.
If this is a suffix cell in a PartyHoursRow or CensusRow,
the value is zero initially. If no effort data ever
gets added to it, it will still be zero. In this
state we will display a hyphen to mean unknown data.
If this is a suffix cell in a PartyHoursRow or CensusRow
and there is any data, the .value
attribute will be a positive float. We'll use
Section 58, “statNumber(): Display a float without
too much precision” to display it with a
reasonable amount of precision.
