Get Single Infoton by UUID

Description

Every infoton has a UUID (UUID = Unique Universal IDentifier) field and value, in addition to having a unique URL. The UUID is used to differentiate among different versions of the same infoton. As CM-Well maintains an immutable-data principle, every time an infoton is updated, a new version of it is written, with a new UUID.

You can retrieve all historical versions of an infoton by performing a GET action on it while using the with-history flag. Once you have the list of versions, you can retrieve each version using a special path composed of the ii endpoint and the UUID value.
