CASSANDRA-3885

I realize multiple people may be working on this, so maybe some discussion
would help?

CASSANDRA-3885 

Should we just copy the way this is handled in NamesQueryFilter? Or am I
missing something obvious?

In the sense that you have a collection of columns to select from the
given row, yes, this is pretty straightforward.  The only real wrinkle
is, it's clear that you need pairs of start + end columns to select,
but what about count?  Should there be a sub-count per slice, or one
master count for the entire filter?

I can't seem to divine from the code what count is being used for. Is it
describing the number of elements that are being accessed? Is it the third
dimension on the columns being accessed?

On another note, and I asked something about this earlier, but I may have
been using the wrong terminology: Is there a preferred way to store these
pairs of start and end columns? A list? A sorted set? should the elements
be stored in pairs? or just assumed to be put into the list/set in pairs?
