/**
 * @fileOverview This javascript handles different actions to perform after shopper selects to proceed with checkout.
 * In summary, user can have different logon status and user can select different shopping option (buy online or 
 * pick up at store). 
 * A user can have the following logon status:
 * 1. Shopper is a guest user
 * 2. Shopper has a commerce account but is not yet logged on (and would like to log on before user proceeds with
 *    shopping flow)
 * 3. Shopper is already logged on
 * In addition, user can select different shipping options:
 * 1. Shop online
 * 2. Pick up at store
 * Every logon status/shipping selection combination as mentioned above will be handled in this javascript
