%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, we offer an 'S4' class for tall, skinny,
distributed matrices, called the 'shaq'.  We also provide many useful
numerical methods and statistics operations for operating on these
distributed objects.  The naming is a bit "tongue-in-cheek", with the
class a play on the fact that 'Shaquille' 'ONeal' ('Shaq') is very tall,
and he starred in the film 'Kazaam'.
