added docstring for tied_biases

[tejaskhot]

Solved issue #722

[tejaskhot]

@dwf @rizar I am a new contributor to blocks and this is my first PR. I verified wth flake8 and pep8 and it passed those tests offline. I cannot understand the Scrutinizer's D504: Docstring exceeds 75 characters error since the docstring for num_channels is actually longer than the one I added for tied_biases

Could you please help me understand how I can check for Scrutinizer and travis issues ? This is new to me so some help at the start will be very much helpful.

It's the actual line length it's complaining about, not the length of the section. The docstring standard we follow specifies 75 characters per line maximum in docstrings. So you'll need to rewrap.

Don't worry about the Travis failure, that looks unrelated (@rizar?).

@dwf It seems solved...can be merged now

LGTM, thanks.
