bool type is not supported

[jkotan]

It is hardly possible to write bool-type fields without converting it into integer. For example

from pninexus import h5cpp

fapl = h5cpp.property.FileAccessList()
fcpl = h5cpp.property.FileCreationList()
flag = h5cpp.file.AccessFlags.TRUNCATE
fl = h5cpp.file.create("bool_h5cpp.h5", flag, fcpl, fapl)

rt = fl.root()

shape = [1, 1]

dcpl = h5cpp.property.DatasetCreationList()

dataspace = h5cpp.dataspace.Simple(
    tuple(shape), tuple([h5cpp.dataspace.UNLIMITED] * len(shape)))

chunk = shape
dcpl.layout = h5cpp.property.DatasetLayout.CHUNKED
dcpl.chunk = tuple(chunk)

field = h5cpp.node.Dataset(
    rt, h5cpp.Path("bool3"), h5cpp.datatype.kInt8, dataspace,
    dcpl=dcpl)
field.write([[True]])
fl.close()

throws

Traceback (most recent call last):
  File "bool_h5cpp.py", line 24, in <module>
field.write([[True]])
  File "/usr/lib/python2.7/dist-packages/pninexus/h5cpp/node/__init__.py", line 276, in dataset_write
memory_type = datatype.kFactory.create(data.dtype)
  File "/usr/lib/python2.7/dist-packages/pninexus/h5cpp/datatype/__init__.py", line 71, in create
return self.type_map[dtype.name]
KeyError: 'bool'

It is somehow related to ess-dmsc/h5cpp#354 and ess-dmsc/h5cpp#260
