Sample usage:

import { UniswapPair, ChainId as UniswapChainId, UniswapPairSettings, UniswapVersion, TradeDirection} from 'simple-quickswap-sdk';


const uniswapPair = new UniswapPair({
    // the contract address of the token you want to convert FROM
    fromTokenContractAddress: token1Address,
    // the contract address of the token you want to convert TO
    toTokenContractAddress: token2Address,
    // the ethereum address of the user using this part of the dApp
    ethereumAddress: '0x207ca4370639120f9A049aF9CAB4fCaa608F2445',
    // you can pass in the provider url as well if you want
    providerUrl: Provider.PolygonMainnet,
    chainId: QuickChainId.MATIC,
    settings: new UniswapPairSettings({
      uniswapVersions: [UniswapVersion.v2],      
    })
  });
  const UniswapPairFactory = await uniswapPair.createFactory();
  const tradeRoutes = await UniswapPairFactory.findAllPossibleRoutesWithQuote('1',TradeDirection.input)
