the "_Tuner_", a programmable, transaction-based Uniswap V3 Simulator with 100% Precision

> Before an ochestra, every musical instrument has to be _in-tune_, to ensure an outstanding performance.
>
> Before running a strategy, every parameter has to be _fine tuned_, to maximaze the performance.

#### _Tuner_ is a programmatic Uniswap V3 simulator that allows strategy backtesting on a transaction-to-transaction basis with arbitrary or historical data without the EVM, it runs independently yet completely retains the exact smart-contract behavior of the intricate design and implementation of Uniswap V3.

#### _Tuner_ is fundamentally a state machine, it can:

> Completely replicate the tick-level calculation

- this means your strategy will run through the Uniswap V3 implementation logic instead of just the high-level mathematic model.

> Maintain the identical tick-level percision of prices, fees, and positions of Uniswap V3

- this means the result of your backtesting is true to the real performance with the minimum margin of deviations.

> Run fast

- the EVM is slow, the historical dataset is huge, the Ganache cannot do the job, so use _Tuner_.

> Fast-forward and rewind transactions

- this means you can easily repeat a small portion of your test with a different set of parameters without the need to start over.

> Take or recover from a snapshot(state)

- this means you can run continuous regression test as your strategies constantly evolves.

> Branch out and runs in parallel

- this means you can run multiple back-tests each with a different set of parameters at the same time and compare the performance.

> Persist historical data and strategy execution records in a SQLite database

- this means the strategists can do advanced statistical analysis both in real-time and after the testing.
