Scoring and Scheduling Constraints

My work during the last two weeks has been on writing a separate scorer as well as writing the scheduling constraints that will allow a scheduler to group blocks together. I also would really like to see the features included in Stuart Littlefair's work be able to be merged into the astroplan master, and so I've been trying to work on finding the issues preventing the package template update from being merged. There are still some issues left that I am not sure how to fix, which may partially result from my attempt at fixing it.
