 - slocum/__init__.py
   - Final alignment of data types: rt, rtd, delayed
 - bin/convertDbds.sh
   - platform compatability fix for unit tests (see below)
 - tests/test_slocum.py tests/test_watch.py
   - do additional clean up of cache files after test completes

Unit tests failed on different platforms due to either magic
or operational diffences of file.  Testing for data or ASCII
allows all the unit test to successfully pass.

-    ftype=$(file $dbdSource | grep data);
+    ftype=$(file $dbdSource | grep 'data\|ASCII');
