0.7.3

Spatial queries are now available using the bound function. Note: datasets retrieved from the CosmoExplorer online query tool prior to the release of 0.7.0 will not contain the necessary information for spatial queries.
You can now create YT datasets out of StructureCollections using for visualization purposes using opencosmo.analysis.create_yt_dataset()
Columns can now be added to a dataset by combining columns that already exist in the dataset. These new columns transform under changes of unit convention and can be filtered on. See Creating New Columns
Structure collections can now contain other structure collections. For example when iterating through halos, you might recieve a StructureCollection of galaxies that are hosted by the given halo.
The names of the columns in a dataset can now be directly accessed with opencosmo.Dataset.columns

opencosmo.StructureCollection.objects() now simply returns a single dictionary, rather than a tuple (note, this is a breaking change). See Structure Collections
You can now use opencosmo.StructureCollection.halos() or opencosmo.StructureCollection.galaxies() in place of opencosmo.StructureCollection.objects based on depending on the type of structures in the collection.

Output handling has been rewritten from the ground up, and is now much more well-behaved particularly in MPI contexts.
MPICH-enabled containers with OpenCosmo and parallel HDF5 installed are now available on DockerHub at astropatty/opencosmo

Fixed a bug that caused StructureCollections to not write properly in MPI contexts
Fixed a bug that that could cause memory overflow when writing large colelctions.

opencosmo.read is now deprecated and will be removed in a later version, use opencosmo.open()
Native Windows support has been dropped due to the addition of healpy as a dependency. Windows use via WSL is unaffected.
