Select the father for the summary view. This should be called on a Person record that
 contains a person id and version.

 Make sure you set both the mother and father before saving the person. Otherwise you will
 set a single parent as the summary.

 ====Params
 <tt>person_id</tt> - the person id of the father that you would like to set as the summary

 ===Example
   person = com.familytree_v2.person 'KWQS-BBR', :names => 'none', :genders => 'none', :events => 'none'
   person.select_father_summary('KWQS-BBQ')
   person.select_mother_summary('KWQS-BBT')
   com.familytree_v2.save_person person

 This is the recommended approach, to start with a "Version" person (no names, genders, or events)
