OpenSpiel 0.1.0
Release 0.1.0
This is our first release since we initially released OpenSpiel in August 2019.
The main purpose is to provide a stable version for anybody currently using the code base for research, or any other form of dependency, as we are planning a number of changes that could be disruptive. Please see #166 and #238 for details.
