Description: 
   This package provides the core functionalities of the GTA (Generate, Test, and Aggregate) programming framework on Haskell (c.f., Kento Emoto, Sebastian Fischer, Zhenjiang Hu: Generate, Test, and Aggregate - A Calculation-based Framework for Systematic Parallel Programming with MapReduce. ESOP 2012: 254-273. The authors' version is available at <http://www.ipl-lab.org/~emoto/ESOP2012.pdf>). 
   .
   /Example/
   .
   The following code is a GTA program to solve the 0-1 Knapsack problem (<http://en.wikipedia.org/wiki/Knapsack_problem>). It /appears to be an exponential cost/ proram in the number of input items, because it appears to generate all item selections by @subsP items@ (/Generate/), discard those with total weight heavier than the knapsack's capacity by @`filterBy` weightlimit capacity@ (/Test/), and take the most valuable selection by @`aggregateBy` maxsumsolutionWith getValue@ (/Aggregate/). However, it /actually runs in a linear time/ owing to our proposed program transformation 'Filter-embedding Semiring Fusion' implemented in the library. In addition, it runs in /parallel/ so that you can get linear speedup.
   .
   > knapsack capacity items = 
   >  subsP items 
   >  `filterBy` weightlimit capacity
   >  `aggregateBy` maxsumsolutionWith getValue
   > 
   > getValue (_, v) = v
   > getWeight (w, _) = w
   >
   > weightlimit w = (<=w) <.> weightsum where
   >   weightsum = homJ' times single nil
   >   x1 `times` x2  = (   x1 +    x2) `min` (w+1)
   >   single i  = getWeight i `min` (w+1)
   >   nil = 0
   .
