Edits to address PR issues; change license from apache to AGPL; and work
...
towards generic method polling and reposito;y; config settings to
filterevents/methods by account address; refactoring some stuff out of
repo and into converter; remove fetcher and instead call
blockchain's FetchContractData directly; finishing tests

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.

change transformer interface and watcher so that contract config is now fed into AddTransformers such that a single watcher can be loaded with transformers that use different cofigs

adjust retriever to pull token holder addresses from Transfer and Approval events (iterating over Approvals might be redundant); edit Makefile to import new missing dependencies of go-ethereum/accounts/keystore, organizing mocks and adding event related mocks and filters

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.

retriever for generating list of all token holder addresses + updated transformer to use said addresses to populate balanceOf and allowance information and added database migrations for balance and allowance tables

fixed tests for getting balanceOf and allowance, added balanceOf and allowance to the repo and repo tests and updated sql schema with new token_balance and token_allowance tables to accept this data

Moved fetcher to generic directory (methods have to remain public since it is in seperate package now), added FetchHash method, created ERC20 and generic getters which call the fetcher with specific contract methods (GetTotalSupply, GetBalance, GetAllowance for ERC20 getter, and GetOwner, GetStoppedStatus, GetStringName, GetHashName, GetStringSymbol, GetHashSymbol, and GetDecimals for generic getter). Getter tests cover all but GetBalance and GetAllowance, and also cover all of the Fetcher methods- but with only nil methodArgs. GetAllowance and GetBalance tests are not working against infura and these are the only contract method calls with arguments passed in so I suspect this might be where the issue lies. Have tested GetBalance using previous version of FetchContractData without the variadic input to the Pack method and it fails with the same error so I don’t think it is due to those changes.

Consolidate test doubles
...
- Migrate various mocks of core namespaces to shared version in `fakes` pkg
- Err on the side of making test doubles less sophisticated
- Don't pull over mocks of namespaces that are only used in example code

Add light sync command
...
- Only syncs block headers (excludes block bodies, transactions, receipts, and logs)
- Modifies validation window to include the most recent block
- Isolates validation window to the variable defined in the cmd directory (blocks
have a separate variable defined in the block_repository for determining when
to set a block as final)

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
