Just pushed a new release, fixing some glitches found in the previous
one and tweaking some features:

New Features:

- SumTrees now allows ``e remove`` / ``edges=unweighted`` to
strip edge length information from output trees.
- NexusReader now processing "ASSUMPTIONS" and "CODONS"
blocks in addtion to "SETS" blocks for character set
information.

Changes:

- SumTrees now will not write edge lengths if none of the
input trees have length information for that edge
(previously, SumTrees would write "0.0" for the edge).

Bug Fixes:

- NexusWriter (and hence SumTrees) does not write an
extra-semicolon after each tree statement (which confuses
some applications, e.g. FigTree).
