%description
Many data science problems reduce to operations on very tall, skinny
matrices.  However, sometimes these matrices can be so tall that they
are difficult to work with, or do not even fit into main memory.  One
strategy to deal with such objects is to distribute their rows across
several processors.  To this end, kazaam offers an 'S4' class for
tall, skinny, distributed matrices, called the 'shaq' and provides
many useful numerical methods and statistics operations for operating
on these distributed objects.
