R versions of statserver analytics

The files were written to replace the statserver analytics on the VDC.
They were originally written to run through an HTML interface (via
Plone).  The code itself should prove useful for standalone R versions.
Added Dale's script for clam reporting
Push Reports added

These are used by the folks in OCMD.  This was added from the server
that runs it, modified to remove passwords.
Simple readme for R folder
Port Samples Push Report added

Not fully developed - it's a modification of the Oceans push report.
