The cool thing about this approach is that it makes a common interface
for two different types of arrays.  In fact, if we were to add more C
datatypes to our wrapper file, the Tcl code would work with those as
well--without modification.  If an unsupported datatype was requested,
the Tcl code would simply return with an error so there is very little
danger of blowing
