Missing Chapter: Order

The readme does not mention how to use order method
So let's write it ourselves!

Basic

Just like where{column}, we write order{column}, done XD

Direction

Actually you can find more in these files:

• https://github.com/ernie/squeel/blob/master/lib/squeel/nodes/order.rb
• https://github.com/ernie/squeel/blob/master/lib/squeel/nodes/ordering.rb

Most useful methods: asc, desc So just write them like order{column.asc} and order{column.desc}, done!

Multiple Columns

1. Pass in array:
   order{[first_name.asc, last_name.desc]}
2. Method chain:
   .order{[username.asc, id.desc]}.order{[first_name.desc, last_name.asc]}
