This test is very sensitive to numerical errors and is thus
not a good test of the code.  The functionality that is
being tested here is tested elsewhere.

Note changes to many regtests are because of changes in labels of
components

A component called "bias" is needed for replica exchange to work properly

Notice that latex cannot be used in captions
