   This will result in less error when the labile formula is used in lieu
   of the natural formula or the contrast-matched formula, and make it more
   obvious from glancing at the formula that labile hydrogen is present.
-* Modify biomolecule object attributes, dropping *Hmass* and *Hsld*.
-* *Hnatural* has been moved to *natural_formula*. The formula with labile
-  hydrogen is stored in *labile_formula*. *formula* is currently set to
-  *labile_formula* as before.

 * Neutron wavelength now defaults to 1.798 A when wavelength and energy are
   both None in *neutron_sld()* and *neutron_scattering()* rather than
   throwing an assertion error.
-* Switch unit test framework from nose to pytest.
 * *table* can be passed to neutron sld calculators as the source of isotope
   information when parsing the chemical formula.
