* Added a prehook _strip option for ALL string validators. The option is True by default and will invoke the strip() validator on all string validators.
* Added the following filter modules [casting, chrono, collection, logical]
* Added tests for strings.canonize and strings.slugify
* Fixed the web.ipv4 validator so that it actually verifies the values of the octets :0
* Added the following filters: [casting.boolean, casting.jsbool, casting.strbool, casting.integer, casting.longint, casting.numeric]
* filters continued: [web.url, casting.string, chrono.date, chrono.time, chrono.datetime, chrono.time_before, chrono.time_after, chrono.time_between]
* Added a schema-level match option used like so: s = Schema('my_schema', match={'password': 'password_confirm'})
* Changed the name of the strings.numeric validator to strings.numeric_string to differentiate it from the casting.numeric filter. Remember that filters are thrust into a global namespace as part of the API's brevity.
* Added tests for the chrono module
* Added in travis-ci with coveralls and pypins
