[Biopython] Biopython 1.63 beta release

[Tiago Antao]

Dear Biopythoneers,

A beta release for Biopython 1.63 is now available for download and
testing.

This is a beta release for testing purposes, the main reason for a
beta version is the large amount of changes imposed by the removal of
the 2to3 library previously required for the support of Python 3.X.
This was made possible by dropping Python 2.5 (and Jython 2.5).

This release of Biopython supports Python 2.6 and 2.7, and also Python
3.3.

The Biopython Tutorial & Cookbook, and the docstring examples in the
source code, now use the Python 3 style print function in place of the
Python 2 style print statement. This language feature is available
under Python 2.6 and 2.7 via:

    from __future__ import print_function

Similarly we now use the Python 3 style built-in next function in
place of the Python 2 style iterators' .next() method. This language
feature is also available under Python 2.6 and 2.7.


Many thanks to the Biopython developers and community for making this
release possible, especially the following contributors:
