Test
sqrtPriceX96
get tick from sqrt price x 96
get price from sqrt price x 96
tick bitmap
getSqrtRatioAtTick
getTickAtSqrtRatio
getAmount0Delta, getAmount1Delta
liquidity delta
tick, liquidity, price directions and token 0 token 1
getNextSqrtPriceFromAmount0RoundingUp(
getNextSqrtPriceFromAmount1RoundingDown
why fee = amountIN * fee / (1 - fee)
nextInitializedTickWithinOneWord
liquidityNet
fee growth (per liquidity)
how does burn update tokensOwed
