[IPT] Generation of GUIDs in IPT

[Tim Robertson]

Hi Steve,

Currently the IPT will reuse an existing GUID if one is mapped to the  
original source (e.g. you map it), otherwise it will create a UUID for  
the record.  It stops short of assigning an actionable GUID at the  
moment, but in the future will do.

A UUID can be "resolved" at the IPT installation (e.g. http://ipt.gbif.org/occ/67f54dd8-aabe-4b8c-84dd-e7618ff23253 
  or http://ipt.gbif.org/occ/67f54dd8-aabe-4b8c-84dd-e7618ff23253/xml)

Note that you need to know the IPT installation address to resolve the  
UUID currently, so they merely 'uniquely identify' records today, but  
are not 'actionable'.

Best wishes,
Tim
