feature_creep

I've got your feature flags implementation right here.

This is a fork/rewrite of James Golick's Rollout with messy and incomplete docs.

So far, the specs are green and are mostly inherited from Rollout. This is not a drop in replacement. The API has already changed.

Namely, groups are now scopes and users are individuals. Agent_ids are expected to be uuids, not the object itself.

There are currently 3 gems in this ecosystem: gem 'feature_creep' gem 'feature_creep-redis' gem 'feature_creep-simple_strategy'

The class constructor now takes

datastore -- FeatureCreep::RedisDatastore is provided with more to come.

info -- should be a lambda that takes two parameters and returns a hash when called

warden -- is also a lambda that takes two parameters and returns a boolean. It encapsulates the business logic for FeatureCreep#active?

options -- an aptly named options hash

options[:scopes] is a hash that expects a string key and a lambda that encapsulates the business logic for membership in a scope

options[:features] is an array of strings or symbols that will add to the list of all possible features.

@feature_creep = FeatureCreep.new(FeatureCreep::RedisDataStore.new(Redis.new,"parent_namespace"), FeatureCreep::SimpleStrategy.warden, FeatureCreep::SimpleStrategy.info, {:scopes => {:some_scope_name => lambda { |individual| User.find(individual).can?(:some_scope) }}, :features => [:feature_1, :feature_2]})

At this point it should be easy to extend. I would expect the API to stablize over the next couple of weeks.
