Constructor
The constructor is where the flipbook or the zoom viewport is created. Therefore, it's called once and cannot be omitted.
Both the flipbook and the zoom viewport have independent constructors.
Turn Constructor
$(".magazine").turn([options]);
For example:
$(".magazine").turn({page: 1, acceleration: true, gradients: true});
Zoom Constructor
$(".viewport").zoom(options);
For example:
$(".viewport").zoom({flipbook: $(".viewport")});
