move existing cache services to new namespace
new service for grabbing and storing eval detail
query to retrieve evals w/ details

currently not including global eval details
eval service returns properly question and scale

all info required to create the actual evals, except for the course
information that will come separately. Global evals will be part of
another method
Added query to get global evaluation questions

Pulled from cache so just needs to be stored once
move queries into resources
changed global eval query to grab based on scale
