Description

I thought there used to be ConvertTo<string>(N) for BigInt and BigRat.
Maybe there used to be, but they were removed for some reason (e.g. the "convert" family is only for conversion between arithmetic types?)

The doc says to use ostringstream instead; that's inconvenient (needs an extra header included, 3 lines instead of 1 fn call).

Reinstate "conversion" of BigInt and BigRat to string?
What should the fns be called?

I have made a quick impl in file decimal.C; its currently called decimals. I had wanted to use DecimalStr but that's already taken (and has a different meaning).

Is decimal.C the right place for such a fn?
What about IntOperations.C? Perhaps that is more for arithmetic?

This has already been done (by me, but I can't recall exactly when).
There is now a template fn called ToString; it is bundled with FloatStr, DecimalStr and ScientificStr in a file called ToString.

Doc & examples have been updated too.
