Merged ./profesores.rb and ./materias.rb and added profesor-subject groupOfNames logic

+ professor        => posixAccount
+ profesor         => posixGroup
+ subject          => organizationalRole
+ profesor-subject => groupOfNames

$ head -n 1 ../profesores2.csv ../materias2.csv
==> ../profesores2.csv <==
RFC,Nombre

==> ../materias2.csv <==
ID,GRUPO,MATERIA,PROFESOR

Notes:
  Student creation will be merged into this script in the near future
  Must write student-group relationship logic
