Program defines the UniformRV class.
This class generates random numbers which are uniformly distributed
in an arbitrary interval (u,v), where u<v.
The parameters u and v are specified in the constructor.
The UniformRV class is also quite simple.
Given that the RandomNumberGenerator class
generates a sequence random numbers uniformly distributed
on the interval (0,1),
the linear transformation
suffices to produce a sequence of random numbers
uniformly distributed on the interval (u,v).
