error in doctool: `param` does not have a `name` attribute

[rekado]

I tried to import coolbox.core.track.base.Track but was greeted with an error in the documentation merging code:

AttributeError: 'tuple' object has no attribute 'name'

This is using the latest release of CoolBox.

The contents of c_params are:

[('properties_dict', 'dict', ["The properties(features) of this track. For example 'height', 'color'..."]), ('name', 'str, optional', ['The name of Track.', '(Default: "{self.__class__.__name__}.{self.__class__._counts}")']), ('title', 'str, optional', ['Title of ax']), ('height', 'int, optional', ['Height of ax']), ('color', 'str, optional;', ['Color of ax'])]
[('file', 'str', ['Path to .bam .sam file.']), ('length_ratio_thresh', 'float', ['Length ratio threshold of show alignments. (Default 0.01)'])]

As can be seen, the second entry does not have a name field.

The second entry appears to come from BAM(Track) in coolbox/core/track/bam.py; so it looks like the doc fields of Track are not inherited in BAM.

Turns out that this problem was due to an older version of numpydoc. Sorry for the noise!
