Dump objects into h5py.Group

[siebenkopf]

I am trying to hickle objects into existing h5py.File objects and put each object into its own Group. Unfortunately, hickle does not allow me to do that.
Here is a minimal example:

import hickle, numpy, h5py
# open h5py file and create a group
h = h5py.File("test.hdf5", 'w')
h.create_group("Array")
# dump data into that group
d = numpy.ones((10,10))
hickle.dump(d, h["Array"])

which raises:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File ".../lib/python2.7/site-packages/hickle.py", line 308, in dump
    h5f = file_opener(file_obj, mode, track_times)
  File ".../lib/python2.7/site-packages/hickle.py", line 163, in file_opener
    raise FileError
hickle.FileError: Cannot open file. Please pass either a filename string, a file object, or a h5py.File

I assume that it should be easy to also accept h5py.Group objects, as they have the same functionality as the h5py.File.

Thanks @siebenkopf , that is an excellent suggestion. There is currently some limited support using the path='/path/to/group', but frankly this isn't particularly well tested, and your use case is neat. Adding it to the todo list in #28!

This has been fixed with the additions I made in #94.
