"""
Results will be returned for each of several trait types: mRNA assays, phenotypes, genotypes, and
(maybe later) genes

For each trait type, the results for each species should be given; for example, have a "Mouse" tab
with the mouse traits in a table inside it

This table will then list each trait, its dataset, and several columns determined by its trait type
(phenotype, genotype, etc)
