reducer

/*
 * projectReducer
 *
 * The reducer takes care of our data. Using actions, we can change our
 * application state.
 * To add a new action, add it to the switch statement in the reducer function
 *
 * Example:
 * case YOUR_ACTION_CONSTANT:
 *   return state.set('yourStateVariable', true);
