What's in a name ?

The 4 views have been shown to be confusing -- it is not clear
to new users what their purpose is, and hence how or why they
are different.

So in an effort to reduce the confusion I've renamed a few
things to be much more explicit and specific.

.. We embrace the fact we are a cycling program and use the term
   RIDES not ACTIVITIES for all files

.. HOME is confusing, renamed to TRENDS

.. the ANALYSIS view name is confusing, its all about ANALYSIS
   to renamed to RIDES

There will no doubt be areas that are not renamed properly we
can fix those when the arise.
