Memory Adapter

@feathersjs/memory is a service adatper for in-memory data storage that works on all platforms. It is normally not used to store data on a production server but can be useful for data that isn't persistent and to e.g. cache data in browser or React Native applications.

$ npm install --save @feathersjs/memory
