Core Pool: A
BPool contract object - this is the "base" pool that actually holds the tokens
Balance: The total token balance of a pool. Does not refer to any user balance.
Denorm: Denormalized weight. Weights on a BPool, though often displayed as percentages, are configured and stored in their denormalized form. For instance, in a two-token pool with denormalized weights of A=38 and B=2, token A's percentage weight would be 38/(38+2), or 95%. Conversely, token B's proportion would be 2/(38+2), or 5%.
Controller: The pool's "owner"; an address that can call
Smart Pool: A contract that owns (i.e., is the controller), of a Core Pool. Much more about these later.
