Package `GeoSciML/Fossil`

The GeoSciML Fossil package contains classes for representing Fossils.
These may be: FossilMold or TraceFossil.
They are linked to living or once living things by the Organism class.

It is recommended that a fossil(s) behaving as a "material" should be described asa "constituent part" of an earth material.

Class Summary
`<<`FeatureType`>>` Classes
FossilMold `<<FeatureType>>`	A fossil that is a negative image of some organism or part of an organism. Considered a structure because the mold has the same relationship to its material substrate that a geologic structure does--the mold is in the substrate, it is not the substrate itself.
TraceFossil `<<FeatureType>>`	A sedimentary structure produced by the life activities (other than growth) of some organism. Neuendorf et al. (2005) restrict to structures produced by animals; further consideration needed on how to deal with structures produced by other life-forms.
`<<`Type`>>` Classes
Organism `<<Type>>`	Broad class to represent any living or once living thing. This is the connection to taxonomy/biology for fossils.
