     * Send to Bill Ferguson, wpferguson@gmail.com
+
+    CHANGES
+    * 20160823 - os.rename doesn't work across filesystems.  Added fileCopy and fileMove functions to move the file
+                 from the temporary location to the collection location irregardless of what filesystem it is on.  If an
+                 issue is encountered, a message is printed back to the UI so the user isn't left wondering what happened.
