This package provides classes which implement extra functionality on top
of the core MBT classes (that is, capabilities that are not absolutely
required by, or would otherwise overcomplicate, the core classes).
This package provides classes which enable molecular biology data
to be represented as visible/renderable viewable objects, plus,
this package defines a top-level StructureDocument object to encapsulate
the complete state of these objects and properties.
This package provides classes which enable molecular biology data sets
(such as protein structures, sequence data, etc) to be loaded into an
MBT application as a Structure object.
