Integrate "Common Data Model" as default result representation for workflow tasks

[GoogleCodeExporter]

ANSTO and Synchrotron Soleil have been working to arrive at a standardized 
representation of data sets, initially to be used in tools/solutions for data 
analysis, to encapsulate the concrete data storage, internal file formats etc.

It consists of a standardized API to work with hierarchic data sets, combined 
with a plugin platform. Plugins serve to provide a bridge between :
- the technical data storage and its specific representation
- and the standardized API.

This API matches quite well with entity models used for Passerelle in several 
projects related to automated diagnostics and decisions, where each workflow 
step (performed by an actor) is represented by a Task entity with its life 
cycle events and its results. The result entities are very similar to the CDM 
API.

We should provide in Passerelle :
- a new result entity model, based on CDM
- persistence options to files and databases maintaining whatever is needed for 
later usage through CDM
- CDM plugin(s) to be able to feed Passerelle results from files and from 
databases into CDM

Got CDMA workspace working, and some sample code running.

This will no longer be continued as the standard impl. At Soleil, CDMA is integrated in their actor libraries and underlying APIs.
