Basic files needed by all Topographica programs.
This package should be self-contained, i.e., should not refer to any other part of Topographica. For instance, no file may include an import statement like ‘from topo.package.module import’ or ‘import topo.package.module’. This policy ensures that all of the Topographica packages outside of this one are optional.
However, this package does depend on two related non-Topographica packages, i.e. param and imagen, and will not work without those being available in the Python path.
