interface to programatically provide custom ticket fields
from trac.core import Interface
class ICustomFieldProvider(Interface):
    def fields():
        should return a dictionary of dictionaries describing the custom
        fields.  The primary key should be the field name.  The secondary keys
        should be the options and the secondary values should be field values
        { 'mycustomfield': { 'type': 'radio',
                             'label': 'My Custom Field',
                             'options': ['foo', 'bar', 'baz']} }
        'type' == 'text' is assumed if not provided
        for defined semantics
