hookup_manager stage one:  New tables for pending and active hookups (pair programming events)

relates to pivotal stories "display list of pending events in a table", 75025008, and "display list of active/live hookups (i.e. hookups with live hangouts) in a separate table",75025492. 
Why is events.create better here?
I thought that FactoryGirl.build_stubbed was faster since it doesn't require the database. *Sampriti had recommended this during our hangout, but he wanted to discuss it with you first if I remember correctly.
