Paolo,

I started on this and then changed my mind about the approach.
These functions obey a scaling law that allows you to scale the 
arguments up by a factor and scale the function by an inverse factor.
I'm going to deploy this solution.

I also need to dig out the asymptotic forms of Bessel functions.

We'll have these in for 4.3 delivery for sure (sooner actually)

On a side note, I started work on accounting for where tr1::regex is in 
the tr1 progress chart.
So unless someone else has done this I'll keep going on it.  It 
shouldn't take long and will help focus effort I think.
