3-way tables are a useful extension of 2-way tables, which are a basic tool for
exploring relationships in data.  R has devised a simple way of displaying
3-way tables in the console.  I don't know what the Multiway Cross Tabulation
(MCT) actor is supposed to do (it is under development?), but it falls under
the Statistics category of Kepler components and the name got me thinking it is
intended for this purpose.  I dunno.  But, if something like ftable() in R is
the intention of that actor, it would definitely be a useful addition to
statistical analyses in Kepler.  If that is not the intention of the MCT actor,
may I suggest an actor that does this.  Specifically, from the R Help:

Displaying a contingency table in this flat matrix form (via print.ftable, the
print method for objects of class "ftable") is often preferable to showing it
as a higher-dimensional array.
