Better Permissions Control

We have introduced 3 new hooks and 2 new middleware as part of feathers-permissions that give you much more flexibility and control over access permissions than was previously possible. Permissions are stored in the database on the entity record that needs to have access permissions checked (typically a user). They look like this:

[
    '*', // all services, all methods, all docs
    'users:*', // all methods on users service
    'users:remove:*', // can remove any user
    '*:remove', // can remove on any service

# Install core dependencies
npm install feathers feathers-hooks

# Install REST and Socket.io
npm install feathers-socketio feathers-rest body-parser

# Install database, error handling, and auth dependencies
npm install feathers-errors feathers-memory feathers-authentication

This all applies to Ruby 2.1. In some cases a setting is not available in 2.0, this is noted. There is also a different with 1.9, 1.8, and REE --- these are not noted.

All the relevant code is in https://github.com/ruby/ruby/blob/trunk/gc.c

RUBY_HEAP_MIN_SLOTS

default: 10000

The number of heap slots to start out with. This should be set high enough so that your app has enough or almost enough memory after loading so that it doesn't have to allocate more memory on the first request (althogh this probably isn't such a big deal for most apps).

(todo: figure out how big a slot is. i think the answer can be infered from this code.)
