 * @title UniswapV2DynamicERC20
 * @notice A dynamic ERC20 token that uses Uniswap V2 to get the current swap price.
 * @dev A UniswapV2DynamicERC20 cannot be minted, burned, or transferred
 *
 * Used within the ProductMint system to act as a proxy for the base token against the quote token.
 * The base token is used to charge for payment.
 * The quote token is used for price targeting.
 * A dynamic price router is used to get the current swap price at a dex such as Uniswap.
 *
 * For example, assume the base token is WETH and the quote token is USDC.
 * An organization can use the DynamicERC20 to create a pricing model that targets a price of 100 USDC.
 * Then, when a user purchases a product, 100 USDC worth of WETH will be transferred to the organization.

/**
 * @dev Contract module that allows children to implement role-based access
 * control mechanisms. This is a lightweight version that doesn't allow enumerating role
 * members except through off-chain means by accessing the contract event logs. Some
 * applications may benefit from on-chain enumerability, for those cases see
 * {AccessControlEnumerable}.
 *
 * Roles are referred to by their `bytes32` identifier. These should be exposed
 * in the external API and be unique. The best way to achieve this is by
 * using `public constant` hash digests:
 *
 * ```solidity
 * bytes32 public constant MY_ROLE = keccak256("MY_ROLE");
 * ```
 *
 * Roles can be used to represent a set of permissions. To restrict access to a
 * function call, use {hasRole}:
 *
 * ```solidity
 * function foo() public {
 *     require(hasRole(MY_ROLE, msg.sender));
 *     ...
 * }
 * ```
 *
 * Roles can be granted and revoked dynamically via the {grantRole} and
 * {revokeRole} functions. Each role has an associated admin role, and only
 * accounts that have a role's admin role can call {grantRole} and {revokeRole}.
 *
 * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
 * that only accounts with this role will be able to grant or revoke other
 * roles. More complex role relationships can be created by using
 * {_setRoleAdmin}.
 *
 * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to
 * grant and revoke this role. Extra precautions should be taken to secure
 * accounts that have been granted it. We recommend using {AccessControlDefaultAdminRules}
 * to enforce additional security measures for this role.
