User Match Preferences

[kentwills]

Currently the matching algorithm in yelp beans can support preferences in two ways:

1. One is a binary option:
   If the preferences don't match then don't match the people together.
   + Guaranteed match based on preference
   - Increased buckets for matching, if a bucket is odd one person doesn't get matched. Number of buckets == the total of potential people that don't get matched. In the extreme case this is very bad for the population.

2. The other is a softer option:
   If two people have preferences toward something in particular, increase weighted edges between the two of them.
   + Smaller number of buckets, less people that don't get matched.
   - won't guarantee a match based on interests
   - you have to source interests or generate a basic list for people to choose from
