[ublas] Array adaptor changes

I have made some changes to the implementation of the array adaptors that were 
defined in "storage.hpp"

Previously 'array_adaptor' and 'shallow_array_adaptor' were defined. They had 
two major problems:
 a) They were never documented or tested
 b) In order to make them Copy Construtable they would allocate their own 
storage. This I think was unacceptable for a standard array adaptor as it 
means that:
        i) They is a runtime overhead associated with tracking which storage was used 
if you used this feature or not
        ii) It is very easy to accidentally perform operations which cause 
construction and then expected changes to the adapted array would not happen.

In new version the two existing classes have been replaces by the simpler 
'carray_adaptor'. This is now fully documented. The changes are committed to 
Boost HEAD so please take a look at the documentation.
