HISTORY: 04/15/2000 initial release
+ 10/25/2001 (RD) Added new variables needed for the non-
+ linear Twin Otter model at zero flaps
+ (CYfxxf0)
+ 11/12/2001 (RD) Added new variables needed for the non-
+ linear Twin Otter model with flaps
+ (CYfxxf). Zero flap vairables removed.
+ 02/13/2002 (RD) Added variables so linear aero model
+ values can be recorded
+ 02/18/2002 (RD) Added uiuc_3Dinterp_quick() function
+ for a quicker 3D interpolation. Takes
+ advantage of "nice" data.
