1.0.4

Enhancements:

• Cache the spec by default when writing a container to disk
• Update the default order of keys of specs written to disk
• Add warnings when an IO operation is not supported in the current mode (e.g. writing in 'r' mode)
• Store the cached spec in UTF-8
• Handle zero-length lists and tuples
• Improve links in documentation
• Passively read datasets that are vectors of strings

Bug fixes:

• Allow boolean attributes in custom classes / get_class
• Write lists of strings in their original encoding instead of ASCII
• Allow a dynamically created container within another dynamically created container to be written to file
• Validate file against cached namespace
• Validate arrays of datetime types correctly
• Properly populate Builder source when reading from HDF5
• Use supplied name for custom classes properly in get_class
• Fix type inference
