Integrate usage example of existing C/C++ PRNGs

[jenetics]

Most of the PRNGs in this libraries are re-implementations of existing PRNGs, described in papers, and implemented in C/C++. The main goal for this PRNGs is to implement them in Java, so they will produce the same sequence of (pseudo) random numbers.
To make it easier to produce such original numbers, the code creating this random number files should be part of the library. It should also possible to build and run this applications with Gradle.
