OCDM Browser 1 Demo

Ported from xiphoid, changed location of SparQL endpoint for OCDM from xiphoid to synapse. Same as original on xiphoid except queries like "View Class hirararcy" on first page don't work because they contact the Query Integrator. But both top level menu items (OCDM browser 1 and OCDM Browser 2) work because they contact the SparQL endpoint on synapse. Screenshots below show example results from xiphoid that no longer work on the synapse port.
