 * @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.
