Data structure implementation

[iredpath]

As an end-user, I would like the application to store all the relevant excel data in some internal data structure. This data will then be used to populate the output file. Should have the ability to set and get data

DoD:

• data structure implemented
• getters/setters added for data access

we can discuss this as a team and decide if it makes sense, but right now the writer is expecting the following function in the data structure API:
Double getVal(Config config);
where config takes the form { statistic: stat, stimulus: stim, subject: subj } (with appropriate getters).
I had a thought just now - if we have an individual cube for SM and LZ data, why do we need a media field? can't we just have the list of stimuli? I'll defer this to Teddy since he has a more thorough vision of the structure than I do, but I don't see where we'll need the media list

we'll want a new subpackage under EDE for this code - I'd suggest calling it "data_structs"
