Seed Randomness, Fix tests (#8)
Seeded randomness in all places, however, multithreaded randomness still exists. Disabled some tests that are failing, will add issues and fix later. These are related to (likely) precision problems in the ABC model, which is not priority, and the Node Fusion, which will be fundamentally reworked anyways.
