Merge pull request #5 from ralusek/types

Better type inference and updated readme to reflect lack of "self" being passed in as argument.

Improvved type inference for cases where tool argument is included. Changed tool argument to be passed push and drain directly, and no longer receives streamie self reference.

1.2.1

1.2.1 built.

1.2.0

Implemented lazy initialization of promise. Added tests ensuring no memory leaks and proper draining.

Fixed types. Introduced change where promise is lazily initialized to avoid unecessary unhandled rejections in cases where promises for parts of the chain were not even being used.

improved upon types to achieve better inference.

added pagination test.

1.0.5

Overhaul to scheduling to use a flattened loop rather than recursive calls in order to process queue items. Should prevent stackoverflows in exessively long runs through consecutive queue items.

1.0.4

Added sensible error propagation.

1.0.3
