I'm having a bit of a brain fart/meltdown here. can someone quickly
show me this (even though I should be able to do it)
given that I have a 4 dimensional matrix. I want to ask for all data
the way I'm thinking about it is this. I'm envisioning a wall with
grid of paned windows in it. To reference a single pane, I would say:
window (3,2), pane (2,2).
What I have is a matrix representing the entire wall, and all I want
is a single window.
