[provenance-challenge] detail on Execute.DeserializeParam

[Paolo Missier]

Hi,
 Yogesh, please note that the method in the subj is declared private 
(unlike SerializeParam).  I just made it public and rebuilt, so no big deal.

I guess no one else has had to use these methods? it turns out they are 
very handy since the Taverna  type system consists of, er, just strings 
(and lists of strings)

Anyone, this reveals that I am still coming to grips with the workflow 
implementation, mostly due to travelling during the past weeks.

Any chance we can push our deadline a tad further, maybe? :-)

Cheers, -Paolo
