For downloading data files on Genotype documents.
Uses the request's GET data to construct a query of the Experiment collection.
Then, for each Experiment, queries the Genotype collection for documents whose
study field matches the Experiment. Constructs a file representation of the query
set(s) (csv format one experiment queried, json format for multiple experiments)

Query parsed from GET data following these rules:
- search_name=[string] : Queries experiments by name
- search_pi=[string] : Queries experiments by primary investigator
- from_date_day=[int]&from_date_month=[int]&from_date_year=[int] : Queries experiments by createddate > from_date
- to_date_day=[int]&to_date_month=[int]&to_date_year=[int] : Queries experiments by createddate < to_date
