Bump the version.
Hopefully this should get it building with Carthage.
Corrects Lagrangian integration.
Adds pairs, suitable for accumulating into dictionaries, and recursive enumeration, suitable for mapping over trees (e.g. view hierarchies).
- phrases the API around a small set of functions.
- is backwards-incompatible.
- is slightly modernized (modern array literals).
Initial tagged release of RXCollections, as prompted by @tonyarnold.
