+ a weighted random sample of a given size based on the A-Res algorithm described in 
+ <a href="http://utopia.duth.gr/~pefraimi/research/data/2007EncOfAlg.pdf" target="_blank">paper</a>.
+
+ <p>
+ Species with larger weight have higher probability to be selected in the final sample set.
+ </p>
+
+ <p>
+ This UDF inherits from <a href="../../../datafu/pig/sampling/ReservoirSample.html" title="class in datafu.pig.sampling"><code>ReservoirSample</code></a> and it is guaranteed to produce
+ a sample of the given size.  Similarly it comes at the cost of scalability.
+ since it uses internal storage with size equaling the desired sample to guarantee the exact sample size.
+ </p>
+
+ Its constructor takes 2 arguments:
+ <ul>
+     <li>The 1st argument specifies the sample size which should be a string of positive integer.
+     <li>The 2nd argument specifies the index of the weight field in the input tuple, 
+     which should be a string of non-negative integer that is no greater than the input tuple size. 
+ </ul>
+
+ Example:
+ <pre>
+ <code>
+ define WeightedSample datafu.pig.sampling.WeightedReservoirSample('1','1');
+ input = LOAD 'input' AS (v1:chararray, v2:INT);
+ input_g = GROUP input ALL;
+ sampled = FOREACH input_g GENERATE WeightedSample(input);

+ Create a new bag by performing a weighted sampling without replacement
+ from the input bag. Sampling is biased according to a weight that
+ is part of the inner tuples in the bag.  That is, tuples with relatively 
+ high weights are more likely to be chosen over tuples with low weights. 
+ Optionally, a limit on the number of items to return may be specified.
+ </p>

+ Example:
+ <pre>
+ <code>

+ 
+ -- input:
+ -- ({(a, 100),(b, 1),(c, 5),(d, 2)})
+ input = LOAD 'input' AS (A: bag{T: tuple(name:chararray,score:int)});
+ 
+ output1 = FOREACH input GENERATE WeightedSample(A,1);
+ -- output1:
+ -- uses the field indexed by 1 as a score
+ -- ({(a,100),(c,5),(b,1),(d,2)}) -- example of random
+ 
+ -- sample using the second column (index 1) and keep only the top 3
+ output2 = FOREACH input GENERATE WeightedSample(A,1,3);
