Add TODO(constantina): ....

Explain briefly that you plan to implement WST here.

[Matt Giuca, 2016/12/08 06:42:56]

Get rid of the string (just "NOTIMPLEMENTED();").

If you look at the log message, it is quite verbose as it is:

[25461:25461:1208/173659.851063:ERROR:share_service_impl.cc(23)] Not implemented
reached in virtual void ShareServiceImpl::Share(const std::string &, const
std::string &, const GURL &, const ShareCallback &)Share called

So there is no need to write "Share called", and FYI if you do, you have to put
a space in front of it or it looks ugly.

Done.

[constantina, 2016/12/09 02:24:14]

Done.

[Matt Giuca, 2016/12/09 02:32:21]

nit: No "@" in the TODO; capital "I" in "Implement".

[constantina, 2016/12/09 03:48:27]

Done.
