<p>Implement this protocol in order to be used within the <code>IGListKit</code> data infrastructure and be registered for use in an

objects.</p>
|

|
|
<p>The infrastructure uses each <code>IGListSectionType</code> conforming object as a <q>view model</q> to populate and control cells as

part of a section in a <code>UICollectionView</code>. <code>IGListSectionType</code> objects should be architected without knowledge of

<p>Index paths are used as a convenience for communicating the section index to each section object without allowing each

section to mutate its own position within a list. The row of an index path can be directly mapped to a cell within

an <code>IGListSectionType</code> conforming object.</p>
