Node Stabilizer (Thaumcraft 4)

The Node Stabilizer is a device added by Thaumcraft 4. It is used to effectively isolate Aura Nodes from the outside environment. When a node is stabilized, it:
 * will not spawn Furious Zombies.
 * will not bully other Aura Nodes and steal aspects from them and vice versa.
 * will not change biomes.

A Node Stabilizer will take energy from the node, halving its recharge rate. It can be turned off with a redstone signal.
