Implement Map/Reduce

[Morgul]

Implement map/reduce functionally, inspired by Riak.

This gist has some ideas.

Your query function returns an array. An empty query returns all objects in the bucket. Unless you want to support browsers that don't natively support map/filter, you're done.

You make an excellent point; I've completely forgotten about filter/map/reduce.

Seems support is nearly universal:

• filter - http://kangax.github.io/es5-compat-table/#Array.prototype.filter
• map - http://kangax.github.io/es5-compat-table/#Array.prototype.map
• reduce - http://kangax.github.io/es5-compat-table/#Array.prototype.reduce

I'm going to close this per offline discussion (to clean up issues list).
