Description

On #60 I realized that there are previous research on this area and this is solved with exact solutions using "Pocock-Simon minimization". [This minimization](https://en.wikipedia.org/wiki/Minimisation_(clinical_trials)) offers exact solutions in some cases (two arms).

There are [some packages on CRAN](https://search.r-project.org/?P=Pocock-Simon+minimization&DEFAULTOP=and&DB=all&FMT=query&xDB=all&xFILTERS=.%7E%7E) that provide it. Specially RobinCar2.

Exploring and see what experDesign can offer compared to that package might be helpful for users and this package.

Research direction

Start with issue #60 and review the linked CRAN search results, especially RobinCar2, to understand Pocock-Simon minimization and its exact two-arm solutions. Compare those capabilities with experDesign and define what this package should offer; done means a documented, agreed scope and an implementation plan.
