Poppins - A checkbox hierarchy manager

Poppins is a minimal checkbox hierarchy manager.

How it works

You need to put the checkboxes inside a div div data-poppins="true", the root checkbox has the tag data-poppins-root="true". Every checkbox needs a unique id that's put on the tag data-poppins-id=<YOUR_UNIQUE_ID> and if it's a child node it also requires data-poppins-parent=<PARENTS_UNIQUE_ID>
