Vote escrow smart contracts

Plenty's ve system consists of several core and associated contracts working in tandem, to play out a model that enables bootstraping of liquidity through a vote-escrow mechanism.

The core contracts handle the base token minting and distribution across Gauges, vote escrow lockups, governance, AMM fee distribution, and deployment of the related core contracts. The Gauge and Bribe contracts are tied to the AMMs, with each AMM having one Gauge and one Bribe contract associated with it.

The AMMs (volatile and stable) are the associated contracts, and they are the primary store of liquidity. From a top level view, the AMMs (associated contracts) are the entities through which all liquidity flows through, and the ve system (core contracts) can direct this flow through its incentivization model.
