/**
* A SlicePredicate is similar to a mathematic predicate (see http://en.wikipedia.org/wiki/Predicate_(mathematical_logic)),
* which is described as "a property that the elements of a set have in common."
*
* SlicePredicate's in Cassandra are described with either a list of column_names or a SliceRange. If column_names is
* specified, slice_range is ignored.
*
* @param column_name. A list of column names to retrieve. This can be used similar to Memcached's "multi-get" feature
* to fetch N known column names. For instance, if you know you wish to fetch columns 'Joe', 'Jack',
* and 'Jim' you can pass those column names as a list to fetch all three at once.
* @param slice_range. A SliceRange describing how to range, order, and/or limit the slice.
