Embed git in package
package.ps1 fetches PortableGit and embeds it in the package. This eliminates all but one runtime dependency (MSVC++ Redistributable). * Move Python into a new FOSS folder.

+Metaclasses
+-----------
+
+Python 3 and Python 2 syntax for metaclasses are incompatible.
+``future`` provides a function (from ``jinja2/_compat.py``) called
+:func:`with_metaclass` that can assist with specifying metaclasses
+portably across Py3 and Py2. Use it like this::
+
+ from future.utils import with_metaclass
+
+ class BaseForm(object):
+ pass
+
+ class FormType(type):
+ pass
+
+ class Form(with_metaclass(FormType, BaseForm)):
+ pass
