Detailed Description

template<class T>
class ShuffledRandom< T >

Routine inspired by examples in "Numerical Recipes" with an extra shuffling of random numbers to avoid sequential correlations.

Used e.g. in generating inputs to avoid potential artifacts. Returns value in open-ended range [0.0, 1.0).

There is technically no reason why this routine would need to be a template, since only type double and (possibly) float are likely to be useful. (It relies on drand48, which uses only 48 bits and thus wouldn't be sufficient for a 64-bit type.) However, the Cray T3E compiler (as of PE3.2) got confused in certain obscure cases when this routine was coded as a regular function in a .c file.
