# gschool_randperson

!! arguments: <gender> <excluded_first_name> <grupTipeEnabled>...
!! gender : 0 for male, 1 for female
!! excluded_first_name : can be '' or you can provide result of previous invocation, so you can compose non-repeating pairs of people
!! <grupTipeEnabled>... : 1 if you include grupTipe, 0 otherwise, look at examples below
!!
!! example:
!! $rand_girl = func('gschool_randperson', 1, '', 1, 1, 0, 1, 0, 0)
!! $rand_girl1 = func('gschool_randperson', 1, $rand_girl, 1, 1, 0, 1)
!!
!! Having grupTipes (social groups)
!! 1 - cool kids
!! 2 - jocks
!! 3 - nerds
!! 4 - Gopnik
!! 5 - outcasts
!! 6 - teachers
!! examples above instruct to choose random person from: cool kids, jocks and gopniks
!! NOTE that in $rand_girl1 zero values for outcasts and teachers are not defined - undefined values will be zero by language
!! Thanks to that you can include new social group and you don''t need to make changes in all places
