 """ this is forms validation classes
 http://formencode.org/module-formencode.validators.html
 for list off all availible validators
 
 we can create our own validators
 
 The table below outlines the options which can be used in a schema in addition to the validators themselves
 pre_validators          []     These validators will be applied before the schema
 chained_validators      []     These validators will be applied after the schema
 allow_extra_fields      False     If True, then it is not an error when keys that aren't associated with a validator are present
 filter_extra_fields     False     If True, then keys that aren't associated with a validator are removed
 if_key_missing          NoDefault If this is given, then any keys that aren't available but are expected will be replaced with this value (and then validated). This does not override a present .if_missing attribute on validators. NoDefault is a special FormEncode class to mean that no default values has been specified and therefore missing keys shouldn't take a default value.
 ignore_key_missing      False     If True, then missing keys will be missing in the result, if the validator doesn't have .if_missing on it already
