#### View.extend(properties) : View
Creates a new child view class and copies the specified properties to the child view prototype.
#### new View(options)
Create a new view instance.
- options.el - The view element - defaults to an empty div
- options.events - The view events to listen for
- options.elements - The view elements to cache
#### view.el : HTMLElement
The view element.
#### view.events : Object
A hash of parameters used to delegate events on child elements of the view element. Hashes are in the format{'event': 'callback'} or {'event selector': 'callback'}.
The callback may be a function, the name of a function which exists as a property on the view, or the string emit: followed by the
name of an event to emit on the view object.
#### view.elements : Object
A hash of selectors used to cache child elements as properties on the view. Hashes are in the format{'selector': 'property'}. Properties prefixed with all: will select all elements matching the selector, not just
the first element.
