Creates a filter object, based on filter options, to notify when the state changes (logs). To check if the state has changed, call eth_getFilterChanges.
Parameters:
fromBlock - Integer block number encoded as a hexadecimal, "latest","pending", or "earliest" tags.
toBlock - Integer block number encoded as a hexadecimal, "latest","pending", or "earliest" tags.
address - Contract address or a list of addresses from which logs should originate.
topics - Array of DATA topics. Topics are order-dependent. Go here to learn more about topics.
Returns:
