[DAS2] "namespace" name

[Andrew Dalke]

I propose using "collection" instead of "namespace"

"namespace" is ambiguous because it means so many things.

Here's what it would look like

       <COLLECTION type="types" id="volvox/1/type">
           <FORMAT name="das2xml" mimetype="text/x-das-featuretype+xml" 
/>
       </COLLECTION>

       <COLLECTION type="properties" id="volvox/1/property">
           <FORMAT name="das2xml" mimetype="text/x-das-property+xml" />
       </COLLECTION>

       <COLLECTION type="features" id="volvox/1/features">
           <FORMAT name="das2xml" mimetype="text/x-das-type+xml" />
       </COLLECTION>

       <COLLECTION type="residues" id="volvox/1/residues">
           <FORMAT name="fasta" mimetype="text/x-fasta" />
           <FORMAT name="raw" mimetype="text/x-raw-sequence" />
       </COLLECTION>

       <COLLECTION type="locks" id="volvox/1/locks" />

Note also that I have a new 'type' field to describe what's
in the collection.  Previously there was no way for a client
to figure out which namespace was which.
