4bb630f93635e7658c2174833e34dd6a77f15ca4,"#1161 WIP to vectorize isel_points (#1162)

* First draft of dask vindex enabled isel_points

WIP to use dask vindex to point based selection

* remove old sel points

* completely re-worked logic

Work to get tests passing - completely re-worked logic to allow for
wide range of Dataset formats and normal behaviour

* improve support for using array dim

* clean up comments

* Still trying to get semantics of dim and coords indexing right

* Tests for sel_points, isel_points working

* clean up comments

* Still trying to get semantics of dim and coords indexing right

* Tests for sel_points, isel_points working

* more tweaks, fixed tests after merge

* revert to origin test now working

* clean up coordinate construction

* further simplify coords construction

* Update tests to require generation of selection axis coordinate array

* revert change to test to reflect latest dataset behaviour

* fix coord generation to match latest dataset behaviour

Datasets no longer require/generate index coordinate for every dimension

* cleanup

* Simplified code by just looping once over variables

* tidy up

* #1162 further improvements

use _replace_vars_and_dims, simplify new dataset creation, preserve
attributes, clarify dim vs dim_name (don’t re-use variable name to
reduce confusion)

* Formatting

* remove impl detail from docstr

* Add performance improvements section and short descr",2017-01-23T20:20:46Z,2017-01-23T20:20:46Z,e52bc11f03b739a273615762c274151fb7e67f37,f10b21bed2846b879806f87039b77245b18e7671,13221727,743508,1217238
