Description

Generating (pseudo) random numbers with controlled seed.

As an extension on top of the C++ random number framework, several instances of random number sequence generators can be easily created with a controlled seed. For simplified usage, two default instances are exposed as global variable

• lib::defaultGen uses fixed seeding (planned: make this configurable)
• lib::entropyGen always uses true randomness as seed value.
