dwhite  length lo hi
diwhite length lo hi

Demand rate white noise random generators.

length  - number of values to create
lo      - minimum value
hi      - maximum value

Dwhite returns numbers in the continuous range between lo and hi,
Diwhite returns integer values.  The arguments can be a number or
any other ugen
