[DAS2] latested dasypus checked in

[Andrew Dalke]

This evening I added checks for:

  - better reporting of where two data structures differ
  - tests for region/
  - a simple test for sequence/
  - workarounds for some gmod problems like

<REGION-LIST
    xmlns="http://www.biodas.org/ns/das/genome/2.00"
    xmlns:xlink="http://www.w3.org/1999/xlink"
     
xml:base="http://http://radius.genomics.ctrl.ucla.edu/das/genome/chado/ 
chado-Hsa-17/region/">


(Should be "REGIONS" and should not have "http://http://")

The architecture is holding up.  There were a few places
where I needed to make stronger checks but the core das2
client API hasn't changed.
