/// @title Feed_Factory
/// @author Stephane Gosselin (@thegostep) for Numerai Inc
/// @dev Security contact: security@numer.ai
/// @dev Version: 1.2.0
/// @notice This factory is used to deploy instances of the template contract.
///         New instances can be created with the following functions:
///             `function create(bytes calldata initData) external returns (address instance);`
///             `function createSalty(bytes calldata initData, bytes32 salt) external returns (address instance);`
///         The `initData` parameter is ABI encoded calldata to use on the initialize function of the instance after creation.
///         The optional `salt` parameter can be used to deterministically generate the instance address instead of using a nonce.
///         See documentation of the template for additional details on initialization parameters.
///         The template contract address can be optained with the following function:
///             `function getTemplate() external view returns (address template);`
