HDF5 Database Store.

|
|
|
shove's psuedo-URL for HDF5 stores follows the form:
|
|
|
|
hdf5://<path>/<group>
|
|
|
|
Where <path> is a URL path to a HDF5 database. Alternatively, the native
|
|
pathname to a HDF5 database can be passed as the 'engine' parameter.
|
|
<group> is the name of the database.
