Represent condition_space and conditions in opil

[tramyn]

Up to this point, @mwes has created a python script to update a structured request generated from Intent Parser with information about conditions and condition_space.
However, now that Intent Parser support generation of OPIL as a second form of output data format for specifying an experimental request, there is a need to generate this same information from Intent Parser so this same information is encoded within opil. Refer to this script to figure out how best to incorporate this into Intent Parser.
