//Takes which token, a strike price(USD per token w/18 decimal places), premium(same unit as token), expiration time(unix) and how many tokens the contract is for

function writeOption(string memory token, uint strike, uint premium, uint expiry, uint tknAmt)

//Purchase a call option, needs desired token, ID of option and payment

function buyOption(string memory token, uint ID)

//Exercise your call option, needs desired token, ID of option and payment

function exercise(string memory token, uint ID)

//Allows option writer to cancel and get their funds back from an unpurchased option

function cancelOption(string memory token, uint ID)

//Allows writer to retrieve funds from an expired, non-exercised, non-canceled option

function retrieveExpiredFunds(string memory token, uint ID)

All uints input (strike, premium, tknAmt) are 18 decimal (meaning 1 is represented as 1e18 or 1 * 10^18) with the exception of expiry which is Unix time formatted.
