Base class describing materials.

Important note about units

Since v6-17-02 the geometry package adopted a system of units, upon the request to support an in-memory material representation consistent with the one in Geant4. The adoption was done gradually and starting with v6-19-02 (back-ported to v6-18-02) the package supports changing the default units to either ROOT (CGS) or Geant4 ones. In the same version the Geant4 units were set to be the default ones, changing the previous behavior and making material properties such as radiation and interaction lengths having in memory values an order of magnitude lower. This behavior affected versions up to v6-25-01, after which the default units were restored to be the ROOT ones.

For users needing to restore the CGS behavior for material properties, the following sequence needs to be called before creating the TGeoManager instance: From v6-18-02 to v6-22-06:

TGeoUnit::setUnitType(TGeoUnit::kTGeoUnits);

From v6-22-08 to v6-25-01:

Connect framework defined extension to the material.

The material "grabs" a copy, so the original object can be released by the producer. Release the previously connected extension if any.

NOTE: This interface is intended for the use by TGeo and the users should NOT connect extensions using this method
