       This subclass of Math::Random::OO generates random numbers with bootstrap resampling (i.e. resampling
       with replacement) from a given set of observations.  Each item in the sample array is drawn with equal
       probability.

"new"
        $prng = Math::Random::OO::Bootstrap->new(@sample);
        $prng = Math::Random::OO::Bootstrap->new(\@sample);

       "new" takes either a list or a reference to an array containing a set of observations and returns a new
       "Math::Random::OO::Bootstrap" object.  If a reference is provided, the object will make an internal copy
       of the array to avoid unexpected results if the source reference is modified.

       If the desired sample is an array of array references, the list must be enclosed in an anonymous array
       reference to avoid ambiguity.

        @sample = ( [ 1, 2, 3], [2, 3, 4] );

        # Correct way
        $prng = Math::Random::OO::Bootstrap->new( [ @sample ] );

        # Incorrect -- will only use [1, 2, 3] as the desired sample
        $prng = Math::Random::OO::Bootstrap->new( @sample );

       It is an error to call "new" with no arguments.

   "seed"
        $rv = $prng->seed( @seeds );

       This method seeds the random number generator.  At the moment, only the first seed value matters.  It
       should be a positive integer.

   "next"
        $rnd = $prng->next();

       This method returns the next random number from the random number generator by resampling with
       replacement from the provided data. It does not take any parameters.
