Detailed Description

Base class for functors on a list of entities.

This class allows splitting an iteration over an ItemVector by ensuring that iterations occur on a multiple of m_block_size. For now, this value is always 8, and thus iterations over entities are done in blocks of 8 values. This allows guaranteeing for vectorization that the sub-views of m_items will be correctly aligned.
