@title Zharta Renting Vault Contract
@author [Zharta](https://zharta.io/)
@notice This contract is the vault implementation for the LOTM Renting Protocol.
@dev This is the implementation contract for each vault, which is deployed as a minimal proxy (ERC1167) by `RentingV3.vy` and accepts only calls from 
    it. This contract holds the assets (NFTs) ) but does not store any information regarding the token, so pre-conditions must be validated by the 
    caller (`RentingV3.vy`). It implement the functions required for token delegation and staking.
Delegations are performed by warm.xyz HotWalletProxy.
