HISTORY: 04/15/2000 initial release
10/25/2001 (RD) Added new variables needed for the non-
- linear Twin Otter model at zero flaps
- (Cnfxxf0)
- 11/12/2001 (RD) Added new variables needed for the non-
- linear Twin Otter model with flaps
- (Cnfxxf). 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.
