[ublas] feature request: BOOST_UBLAS_NDEBUG

    I recently ran some code in debug mode and was astonished at how 
long it took to run.  After profiling I discovered that the bottleneck 
was caused by the uBlas debug macros.  Since I still needed to debug the 
code but couldn't afford to spend 40 minutes on a single test run, I 
manually defined all the uBlas NDEBUG macros to disable the uBlas 
checking while still being able to use the debugger.  This worked, but 
it was extremely inconvenient and time-consuming.

    It would be nice if you allowed users to define a BOOST_UBLAS_NDEBUG 
macro to disable only the uBlas debug macros.  Then in 
boost/numeric/ublas/detail/config.hpp, you can replace the line
        #ifdef NDEBUG
with
        #if defined(NDEBUG) || defined(BOOST_UBLAS_NDEBUG)

and the user will be able to disable the uBlas check macros and still be 
able to debug.
