problems using blitz::TinyVector as key for map

[Faheem Mitha <faheem at email dot unc dot edu>]

Hi,

I'm having problems with using 'find' on a map whose key is a 
blitz::TinyVector<T, N>. See http://www.oonumerics.org/blitz/ for more 
information about the Blitz++ library.

Can anyone tell me if I'm doing something wrong, or is this a bug?

Thanks.                                                    Faheem.
