Simple closed form solution

The `Simple` solution is the simplest among our three closed form
solutions, and the `Complete` and `Positive` solutions will be
built upon the `Simple` solution. Before, presenting the `Simple` solution, we first classify the input distributions. This
classification is used, in particular, to determine the number of
phases used in the `Simple` solution.
