Implement v2

[kennylavender]

Following the proposal outlined in #102

Implement update the following:

• Update Readme
• Components
  • FeatureToggles
  • Feature
• HOCs
  • withFeatureToggles
  • configureFeature
• Functions
  • isActive
  • mergeFeatures
  • deactivateFeatures
  • parseQuery
  • getEnabledFeatures
  • getBrowserQueryFeatures
  • getReqQueryFeatures
• Update Feature Interface
• Remove old code
  • components
  • hocs
  • functions
  • tests
• Update createRouteMiddleware

After these are implemented, we need to build more automation of query parsing and merging of features.

I've done all the PR's I am going to do for now, I want Jesse, once he accepts, to review the current PR's and Pair Program with me on the rest of the v2 changes.

Note to self: after implementing getBrowserQueryFeatures and getReqQueryFeatures it might make sense to rename parseQuery to getQueryFeatures

What needs to be done to get 2.0 out of beta?

I think everything is done except reviewing the express middleware to see if we can make improvements. I've updated the list above
