 Design:
 If the environment variable $HDF5TestExpress is defined,
 then test programs should skip some tests so that they
 complete sooner.

 Terms:
 A "test" is a single executable, even if it contains multiple
 sub-tests.
 The standard system for test times is a Linux machine running in
 NFS space (to catch tests that involve a great deal of disk I/O).

 Implementation:
 I think this can be easily implemented in the test library (libh5test.a)
 so that all tests can just call it to check the status of $HDF5TestExpress.
