Yay

------------------

- Numbers starting 0 are treated as base 8.

------------------

- Avoid unicode mapping keys where possible - they break kwargs in Py2.x

------------------

- Add support for nested foreach

- At least for now, support a ruby style .flatten

------------------

- {foo} can be interpreted as a map by YAML. For now, we will use ${foo} to avoid this

- Function calls to python are implemented - there is now range()

- There is now a foo.select key so switch statements can be used

------------------

- Egg packaging fixes

------------------

- Lots more unittests for expression evaluation and expression parsing

- Drop dependency on OrderedDict
