Bumped version to 0.4.1.2, fixed an issue relating to parents. See #12
Update README.rst
Changed the map_field decorator to assume the method name is the from_field if None is provided.
Updated Resource.convert_to and Mapping.convert to allow field values to be passed in.

This allows fields values to be specified externally from the mapping inline (making it easier to do conversions in a list comprehension)
Merge branch 'master' of github.com:timsavage/odin
Bumped version for a future release
Change crate.io reference to point to pypi.
Added pypy to travis for test cases.
Work around for pint and pypy

Pint does not install on pypy, for these we will not install pypy.
Update .travis.yml
Add missing "; fi" to settings for Travis
Updated test cases to separate contrib tests.

Not all contrib libraries are supported by pypy
Change map functions to treat response of tuples as separate fields and lists as individual fields.
