[chuck-users] .cap() for multi-dimensional arrays

[Mark Pauley]

In some languages (like C) multi-dimensional arrays do need to be  
rectangular.  This is because it's really just one big array.  i.e.  
If you

int foo[2][3];

you're doing exactly the same as

int foo[6];

except that the compiler will do a bit of sugar for you and multiply  
your outer index by the inner array size and add it to your inner index.

In java this is not the case because each index into your outer array  
is infact a ref to an array object.
