This class expects to be run in a directory which contains the subdirectory
structure shown below (where example aircraft X-15 is shown):
<PRE>
aircraft/
X-15/
X-15.dat reset00 reset01 reset02 ...
CDRAG/
a0 a M De
CSIDE/

CLIFT/

The General Idea
The file structure is arranged so that various modeled aircraft are stored in
their own subdirectory. Each aircraft subdirectory is named after the aircraft.
There should be a file present in the specific aircraft subdirectory (e.g.
aircraft/X-15) with the same name as the directory with a .dat appended. This
file contains mass properties information, name of aircraft, etc. for the
aircraft. In that same directory are reset files numbered starting from 0 (two
digit numbers), e.g. reset03. Within each reset file are values for important
state variables for specific flight conditions (altitude, airspeed, etc.). Also
within this directory are the directories containing lookup tables for the
stability derivatives for the aircraft.
