/**
 * Generic Mintable NFT Sale contract
 * Create a collection with the following variables
 * - max supply - max number of nfts
 * - price - per nft
 * - Max items per mint
 * - pre mint - number of NFTs that can be preminted for free, by whitelisted users, or in a batch for admins e.g. for giveaways
 * - free mint - number of nfts to allow users to mint for free
 * Allow users to mint for a given price
 * Contract accumulates ETH from sales
 * Accumulated ETH can be withdrawn to a EOA or paymentSplitter to split gains across many users using withdrawAllToSplitter
 *
 * Admins can set the baseTokenURI before or after a drop
 * Setting the baseTokenURI after a drop, allows the contract to sell off NFTs with different rarities with the same price without cheating
 *
 * Advantages:
 - specify a price and change it later
 - create a limited supply collection, and add new items later
 - cheaper than rarible nft factory? 
 - add royalties on opensea and rarible later when the collection is imported
