D.15.12.4 diffAlgebraSwitch

Procedure from library difform.lib (see difform_lib).

Usage:
diffAlgebraSwitch();

Assume:
The differential algebra was already constructed.

Side effects:
Changes the ring: from the basering to the differential algebra.

Note:
whenever computations with differential forms are done, the ring must be changed to the differential algebra since differential forms are polynomials there. But first it should be checked if the algebra is actually available: so before executing diffAlgebraSwitch there should always be an preceding diffAlgebraCheck
