/**
 * A rather exhaustive set of tests. Tests include leaving the ActiveFileName
 * argument blank, or setting it, with and without compression, and tests
 * with or without stopping/restarting the RollingFileAppender.
 * 
 * The regression tests log a few times using a RollingFileAppender. Then, 
 * they predict the names of the files which sould be generated and compare
 * them with witness files.
 *
