@TomNicholas let us know when this is ready for testing - we're also happy to help out with the documentation/example notebooks if that's helpful! cc: @aurghs |

I think this PR is mostly ready to merge, but I want to pin it to the upcoming pre-release of xarray so that the indexing internals are in a well-defined state. This PR also of course depends on #41. |

Initial attempt to change
.dsto instead return an immutable view onto the node's data, instead of a mutable dataset.This closes the part (1) of #80:
That immutability also closes #38.
This PR builds on top of #41.
