feat(associations): many-to-many associations

fix(associations): fix association queries, must use `include` instead of ForeignKey
fix(error): error decorator was missing await, which prevented it from catching errors
fix(error): console.error the error
refactor(crud): don't use `request.models[name]`, use the model directly
chore: README added

+hapi-sequelize-crud
+===================
+
+Automatically generate a RESTful API for your models and associations
+
+This plugin depends on [`hapi-sequelize`](https://github.com/danecando/hapi-sequelize).
+
+```
+npm install -S hapi-sequelize-crud
+```
+
+##Configure
+
+```javascript
+// First, register hapi-sequelize
+await register({
+  register: require('hapi-sequelize'),
+  options: { ... }
+});
+
+// Then, define your associations
+let db = server.plugins['hapi-sequelize'].db;
+let models = db.sequelize.models;
+associations(models); // pretend this function defines our associations
+
+// Now, register hapi-sequelize-crud
+await register({
+  register: require('hapi-sequelize-crud'),
+  options: {
+    prefix: '/v1'
+  }
+});
+```
+
+Please note that you should register `hapi-sequelize-crud` after defining your
+associations.
+
+##What do I get
+
+Let's say you have a `many-to-many` association like this:
+
+```javascript
+Team.belongsToMany(Role, { through: 'TeamRoles' });
+Role.belongsToMany(Team, { through: 'TeamRoles' });
+```
+
+You get these:
+
+```
+# get an array of records
+GET /team/{id}/roles
+GET /role/{id}/teams
+#might also append query parameters to search for
+GET /role/{id}/teams?members=5
+
+# get a single record
+GET /team/{id}/role/{id}
+GET /role/{id}/team/{id}
+
+# create
+POST /team/{id}/role
+POST /role/{id}/team
+
+# update
+PUT /team/{id}/role/{id}
+PUT /role/{id}/team/{id}
+
+# delete
+DELETE /team/{id}/roles #search and destroy
+DELETE /role/{id}/teams?members=5
+
+DELETE /team/{id}/role/{id}
+DELETE /role/{id}/team/{id}
+```
