%TestSuiteInDir Test suite requiring temporary directory change
%   The TestSuiteInDir class defines a test suite that has to be run by first
%   changing to a specified directory.
%
%   The setUp method adds the starting directory to the path and then uses cd to
%   change into the specified directory.  The tearDown method restores the
%   original path and directory.
%
%   TestSuiteInDir methods:
%       TestSuiteInDir  - Constructor
%       gatherTestCases - Add test cases found in the target directory
%
%   See also TestSuite
