Subject: Move the DIS benchmarks up a directory and update hardcoded paths

Note that this repo does not attempt to keep a copy of the original
DIS benchmark distributions. UNC real-time has another repo for that.

+/*
+ *  Sample code for the DIS Transitive Stressmark
+ *
+ * This source code is the completely correct source code based on 
+ * the example codes provided by Atlantic Aerospace Division, Titan 
+ * Systems Corporation, 2000.
+ * 
+ * If you just compile and generate the executables from this source 
+ * code, this code would be enough. However, if you wish to get a complete 
+ * understanding of this stressmark, it is strongly suggested that you
+ * read the Benchmark Analysis and Specifications Document Version 1.0
+ * before going on since the detailed comments are given in this documents.
+ * the comments are not repeated here.
+ *
+ * CHANGELOG:
+ * Joshua Bakita, 05/30/2020: Fixed out-of-bounds randInt call
