new student controller, lists/gets evals

returns json so we can debug, gets students by loginId, gets eval by
Guid property and returns a full object so we can pose questions
added in emulation so we can test being students
determine open evals by inspecting start/end
change to manual join to get open evals faster
project evals to model so we have course info

show students: {name} ({subject} {coursenumb}) and then classType
added new index and student specific layout
group classtimes by course, show nested
displays class evals w/ link, grouped by course
created sections for global q's and other q types

global are not asked per-person, formatting needs lots of help, but
basic questions are setup properly
rework query to get course info

display that info on the eval page so students know what they are
