This is step one in unwinding the Environment class.  It moves to
an object stored in a static variable, and everything is built
off of that.  I included one example of how the new-style will
be used.  Converting the zillion other uses will be follow-up
issues.  The static methods should also get marked deprecated
to point people toward the object properties.
