weighted source distribution

Source distributions define how records are selected from a source pool.

Illustrative behavior

Source distributions define how records are selected from a source pool. SOURCE POOL A B C D GLOBAL SELECTION A A C A B A A B

This is a representative seeded illustration. Exact output depends on rngSeed, the source, and the remaining runtime inputs.
