Adding gsml GeotechUnit

Position in GeoSciML

The proposal is to have gsml:GeotechUnit defined as a specialization of gsml:GeologicUnit

In GeoSciML, the concept of Geologic Unit is defined as "a package of earth material" (see: https://github.com/opengeospatial/Geotech/wiki/GeologicUnit).

To offer some variations of the Geologic Unit concept, CGI introduced Geologic Unit types.

The proposal is to add a Geologic Unit type entitled GeotechUnit which would follow this definition:

A geologic unit defined by its geotechnical properties

For which geotech concept do we want to use gsml:GeotechUnit?

gsml:GeotechUnit is identified to realize the geotech concept called GeotechUnit.

Geotechnical properties

A GeotechUnit being a GeologicUnit, it inherits of its properties.

Additionnal properties specific to the Geotech Unit includes:
