Add ERC20 token watcher example - starting with the totalSupply function - sets contract config on transformer by passing it into the transformer initializer - handles block records with the same number for different nodes for both creating token_supply records, and finding missing blocks

work on erc20 event_triggered functionality and generic helper for log unpacking and converting. helpers.ConvertToLog and helpers.createTopics have been adjusted to be variadic to work with event logs with any number of topics. Also uncovered issue with Dai and TrueUSD that means they doesn't really conform to the ERC20 standard. this is because they named their arguments to standard events like Approval and Trasnfer differently (e.g. Approval(src address, guy address, wad uint) and Approval(owner address, spender address, value uint) instead of the standard which is Approval(tokenOwner address, spender address, tokens uint)). This causes incompatibility with generic ERC20 entities and converters for these events.

beginning work on method polling; first need to generate list of token holder address in a completely generic/contratc agnostic fashion. Created address retriever that can iterate through any given contract's watched events, finding the inputs/arguments with address type, and generate a list from those values. Edit: Contract objects now cache every event emitted address as its event logs are transformed into the repo to grow a list of contract associated addresses as we go

Generic watcher that takes a contract address, grabs the contract abi and starting block number, creates custom event filters, and extracts and transforms event data into postgres. Can configure to look at only a subset of events through CLI flag. Building but needs testing.
