So, if the package is called "inductive-graphs" place everything in
Then, to use the library I simply need to write "import
InductiveGraphs" (unless I wanted more control over names, and then I
could import individual modules).  In this way, when someone else
decides to write another graph library, they could put it in their own
package namespace, and there would be no need to have this same
discussion again.  This naming convention even supports a single
project using multiple graph libraries, which may be useful if the
different implementations provide different performance trade-offs.
