* @title YearnV3 Base Strategy
* @author yearn.finance
* @notice
* BaseStrategy implements all of the required functionality to
* seamlessly integrate with the `TokenizedStrategy` implementation contract
* allowing anyone to easily build a fully permissionless ERC-4626 compliant
* Vault by inheriting this contract and overriding three simple functions.
* It utilizes an immutable proxy pattern that allows the BaseStrategy
* to remain simple and small. All standard logic is held within the
* `TokenizedStrategy` and is reused over any n strategies all using the
* `fallback` function to delegatecall the implementation so that strategists
* can only be concerned with writing their strategy specific code.
*
* This contract should be inherited and the three main abstract methods
* `_deployFunds`, `_freeFunds` and `_harvestAndReport` implemented to adapt
* the Strategy to the particular needs it has to generate yield. There are
* other optional methods that can be implemented to further customize
* the strategy if desired.
*
* All default storage for the strategy is controlled and updated by the
* `TokenizedStrategy`. The implementation holds a storage struct that
* contains all needed global variables in a manual storage slot. This
* means strategists can feel free to implement their own custom storage
* variables as they need with no concern of collisions. All global variables
* can be viewed within the Strategy by a simple call using the
* `TokenizedStrategy` variable. IE: TokenizedStrategy.globalVariable();.
