Programmatically Expand and Collapse Header View

[ghost]

Hi,

First off, thanks a lot for creating such an awesome library and open-sourcing it.

Moving on, I have a query -- not an issue per se -- regarding the header view. As the subject says, how do I programmatically expand and collapse the header view?

Thanks, Daksh.
