Moved shorthand validator extraction to happen just before validation, reducing cost to initialize form and allow dyanmic Nodes to use shorthand as well.
Extracted safety checking of new nodes to a utility function to be more DRY
Resolved #66, validator shorthands allowed are now correct.
Fixed a problem where mutable attribute overrides were shared by class instances
Added an __iter__ function to Check and Node to reduce checking in insert functions
Fixed bug with default override for 'validators' not 'validator'
Added a config file for Travis CI
Started a major cleanup of the tests with the following key points:
    + Expanded several tests to do more assertions, test more scenarios,
    or cover less code. Many are still fairly sloppy.
    + Rearranged the Form tests to be structured more sensibly.
    + Added a lot of comments, or re-wrote comments to be more
    descriptive
    + Added todos that will be resolved by 0.2.2. These are poorly
    written tests that need to be cleaned up still.
Note: a few tests are currently broken and in the middle of re-write.
Changed a few thing to try and get Travis to work
Continued cleanup of tests. All are passing now, and validator tests are a lot more DRY.
Fixed some pylint and pep8 violations
Continued expansion/organization of test suite.
Added a few tests for areas that were getting coverage, but not a good number of assertions or specific testing targeting.
Further minor re-arranging
Removed some unused imports
Fixed several minor issues with tests created/modified in recent commits.
Added a test to get slightly more coverage.
Made necessary modifications for Python3.3 support
Merge branch 'master' into icook_dev
Fixed executable property in some tests so Nose would run them by default
Reworked the mainpage documentation a bit, as well as expanding the Node.rst section
Removed the PyCaptcha node until we have a chance to get it well integrated
Changed permissions so tests run now...
Merge branch 'icook_dev' of github.com:icook/yota into icook_dev
Rewrote the way inherited class attributed are overriden and copied when new instances are created. Now works exactly as intended even with custom configuration attributes.
Fixed tests associated with the above changes.
Converted override/inheritence of Nodes to match Form objs.
Fixed minor 3.3 typo.
Added a test to ensure Node inheritence as expected.
Resolved #62, new parameters added to Form for overriding redner_success and render_error with ease.
Resolved #52, all builtin nodes now support the parameters 'css_style' and 'css_class'
