/**
 * @title Filtered Minter contract that allows tokens to be minted with ETH.
 * Pricing is achieved using an automated Dutch-auction mechanism.
 * This is designed to be used with GenArt721CoreContractV3 flagship or
 * engine contracts.
 * @author Art Blocks Inc.
 * @notice Privileged Roles and Ownership:
 * This contract is designed to be managed, with limited powers.
 * Privileged roles and abilities are controlled by the core contract's Admin
 * ACL contract and a project's artist. Both of these roles hold extensive
 * power and can modify minter details.
 * Care must be taken to ensure that the admin ACL contract and artist
 * addresses are secure behind a multi-sig or other access control mechanism.
 * ----------------------------------------------------------------------------
 * The following functions are restricted to the core contract's Admin ACL
 * contract:
 * - setMinimumAuctionLengthSeconds (note: this is only enforced when creating
 *   new auctions)
 * - resetAuctionDetails (note: this will prevent minting until a new auction
 *   is created)
 * ----------------------------------------------------------------------------
 * The following functions are restricted to a project's artist:
 * - setAuctionDetails (note: this may only be called when there is no active
 *   auction)
 * - setProjectMaxInvocations
 * - manuallyLimitProjectMaxInvocations
 * ----------------------------------------------------------------------------
 * Additional admin and artist privileged roles may be described on other
 * contracts that this minter integrates with.
 *
 * @dev Note that while this minter makes use of `block.timestamp` and it is
 * technically possible that this value is manipulated by block producers, such
 * manipulation will not have material impact on the price values of this minter
 * given the business practices for how pricing is congfigured for this minter
 * and that variations on the order of less than a minute should not
 * meaningfully impact price given the minimum allowable price decay rate that
 * this minter intends to support.
