/* Further Adventures

 *

 * The User constructor and user view

 * code have been imported on the

 * HTML panel.

 *

 * The user data needs a name and

 * a sessions array.

 *

 * 1) Run the program.

 *

 * 2) At the console, create some

 *    user data:

 *

 *    > var data = { name: 'Bob', sessions: [] }

 *

 * 3) Initialize the fitness app

 *    with the data:

 *

 *    > var user = fitnessApp.init(data)

 *

 * 4) Log a session:

 *

 *    > user.log("2016-09-03", 40)

 *
