Version 0.9.13

The following updates have been made:

1. Version 0.9.12 introduced a feature whereby “large” graphs were never displaced from the cache. This was useful for us where we were computing the polynomial of the Truncated Icosahedron. Furthermore, I made the default setting to automatically determine what was considered a large graph. However, this caused problems when using the tool to run large experiments, where each experiment consisted of several graphs in one batch. The problem was that lots of “large” graphs were getting stuck in the cache, eventually clogging it up. So, I have disabled this default setting. You can still request graphs over a certain size be retained, however, but this must be done explicitly on the command-line.

2. Some of the options listed with tutte --help were wrong, and have been corrected.
