/*%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Module: FGFactorGroup.cpp
Author: Tony Peden
Date started: 7/21/01
Purpose: Encapsulates coefficients in the mathematical construct:
factor*(coeff1 + coeff2 + coeff3 + ... + coeffn)
Called by: FGAerodynamics

FUNCTIONAL DESCRIPTION
--------------------------------------------------------------------------------
This class models the stability derivative coefficient lookup tables or
equations. Note that the coefficients need not be calculated each delta-t.
Note that the values in a row which index into the table must be the same value
for each column of data, so the first column of numbers for each altitude are
seen to be equal, and there are the same number of values for each altitude.
See the header file FGFactorGroup.h for the values of the identifiers.
