yxToken (DyDx tokenization)

yxTokens allow users to earn interests on DAI and USDc via DyDx protocol in an easy and composable way. The contract is used to create ERC20 representing lending positions on DyDx protocol. When you lend assets you will receive yxTokens representing your share of the contract balance in DyDx protocol.
When you redeem funds you will burn yxTokens and unlock your assets + interest accrued.
The yxToken amount when minting is determined by a price taken directly from DyDx (usinggetMarketCurrentIndex method), the price of each yxToken should always increase because it represents the deposited notional + interest accrued.
