Biome Reactors

Biome Reactors adds a sole block: The Biome Reactor. This block allows the exchange of Redstone Flux(commonly referred to as RF) in order to change the biome in a 7 block radius. Different blocks have to be put inside the reactor for each different biome. It usually uses around 400,000 RF to change the biome.

An API for modders who want the machine to be able to convert their own custom biomes is available here: https://github.com/Alex-the-666/BiomeReactorsApi
