The following sub-sections describe the principal geometrical primitives used
n Tina. It is this set of primitives that are managed by the Geomstat

package. The final section describes generic geometry functions that use a
**type** field to determine the which of the geometrical data structures has
been passed as data. These are very useful where a number if different
primitive types are groupd within a more complex data structure, most
typically a recursive list.

- Scalar
- Point Geometry
- Line Geometry
- Curve Geometry
- Plane Geometry
- Transformations
- Generic Geometry Functions
