Binds methods of an object to the object itself, overwriting the existing
method. Method names may be specified as individual arguments or as arrays
of method names. If no method names are provided all the function properties
of `object` will be bound.

@example

var view = {
'label': 'docs',
'onClick': function() { console.log('clicked ' + this.label); }
};

_.bindAll(view);
jQuery('#docs').on('click', view.onClick);
// => logs 'clicked docs', when the button is clicked
