Creating a Data layer - 2.) The Database Context - Inheriting from DbContext

NoteContext.cs

/*
  Entity framework expects a Context class. This class is used to communicate between the code and the dB. Since we built our model
  classes by convention, we won't need to do much in the way of configuration of our context.
  
  This is the pipeline to all queries, inserts, updates, deletes for any data operation is going to be passed through.
  
  *The next class we'll build will be the NoteRepository class to wrap the context in.
