Added schedule for Texas A&M
Conferences and clean up

Added the conferences domain class. Did some clean up on the seed
methods, trying to make it so that when the database is deleted and
recreated, it gets created the first time with out errors. I was able to
remove some of the initial errors, but not all. Still have some work to
do there. Also added some conference seed data.
Excel Schedule

Created new Excel Schedule class to help with the mass importing of the
excel schedule. Procedure will be to import the excel file to this table
in the database, get all information to match from import to current
college data, then build a script that will create a the schedule based
on this import. Also stated to clean up College data based on initial
import.
