example:

   INPUT(_type='text', _name='name', requires=IS_NOT_EMPTY())

   >>> IS_NOT_EMPTY()(1)
   (1, None)
   >>> IS_NOT_EMPTY()(0)
   (0, None)
   >>> IS_NOT_EMPTY()('x')
   ('x', None)
   >>> IS_NOT_EMPTY()(' x ')
   ('x', None)
   >>> IS_NOT_EMPTY()(None)
   (None, 'enter a value')
   >>> IS_NOT_EMPTY()('')
   ('', 'enter a value')
   >>> IS_NOT_EMPTY()('  ')
   ('', 'enter a value')
   >>> IS_NOT_EMPTY()(' \n\t')
   ('', 'enter a value')
   >>> IS_NOT_EMPTY()([])
   ([], 'enter a value')
   >>> IS_NOT_EMPTY(empty_regex='def')('def')
   ('', 'enter a value')
   >>> IS_NOT_EMPTY(empty_regex='de[fg]')('deg')
   ('', 'enter a value')
   >>> IS_NOT_EMPTY(empty_regex='def')('abc')
