"""A Material object is the object used to specify a material. The Material object stores
the various settings that determine how a material behaves.
A material is created by combining one or more individual material options and sub
options. A particular material option is associated with the Material object through a
member. For example: the *acousticMedium* member may contain an AcousticMedium object.
The alternative of having a MaterialOption abstract base class and a container of
MaterialOptions was rejected because it would make it more difficult to enforce the fact
that one Material object cannot contain two AcousticMedium objects, for example.
