Note that inheriting from components works differently than other CanJS APIs. You can't call
.extendon a particular component to create a "subclass" of that component.Instead, components work more like HTML elements. To reuse functionality from a base component, build on top of it with parent components that wrap other components in their template and pass any needed viewModel properties via attributes.
