Is it possible to cast object into a multidimensional array?  Malloc a multidim. array?  What 
is the syntax?

The problem where I see this arising is when I try to "reuse" code.  Some people are religious
about flexibility and use pointers, and arrays of pointers to implement multidimensional
arrays, others coming from the FORTRAN world like clarity and define everything at compile
time and publish dimensions in their #include's.

Both have their advantanges.  I have my preference but who cares.  The problem is when the two
collide its like matter and anti-matter.  Wholescale copying is painful, especially when the data in 
data object is arranged just like a multidimensional array would be.

I would also love to hear exactly how a multidim. array is actually stored i.e. there must be some
overhead stating what the innermost dimensions are.  How is that stored.  Is it physically stored as
a header to the data?
