Uniform distribution.
The Uniform class implements a uniform random variable over the copen interval ranging from [low..high). The low parameter is the lowest possible return value and the high parameter can never be returned. The operator() functions returns a value from this distribution.
It is assumed that low limit is less than the high limit and an AipsError exception is thrown if this is not true. The remaining members allow you to read and set the parameters.

Construct a random number generator for a uniform distribution.
The first argument is a class that produces random bits. This pointer is NOT taken over by this class and the user is responsible for deleting it. The remaining arguments define the parameters for this distribution as described in the synopsis.
