Set the radio button group

If we make more than one input option, then we have to create a group for each of these inputs.

ui_radio_set_group (control group);

Return: True if successful

Argument control is the handle of ui_radio_create(...);. argument group can be a string or a real number.

optionMale = ui_radio_create (64, 100, ui_default, "Male");
ui_radio_set_group (optionMale, "gender");
optionFemale = ui_radio_create (200, 100, ui_default, "Female");
ui_radio_set_group (optionFemale, "gender");

optionRegular = ui_radio_create (64, 132, ui_default, "Regular Member");
ui_radio_set_group (optionRegular, "member");
optionPro = ui_radio_create (200, 132, ui_default, "Professional Member");
ui_radio_set_group (optionPro, "member");

Make two inputs radio button group of "gender" and "member".
