Use include(...) for urlpatterns

[helper08]

Currently, there is a lot of redundancy in our urlpatterns as we repeat a lot of prefixes for url groupings. This could be made cleaner by using include(...)

For example, for the Secretary urls:

url(r'^secretary/$', views.secretary, name="secretary"),
url(r'^secretary/positions/$', views.secretary_positions, name="secretary_positions"),
url(r'^secretary/positions/add/$', views.secretary_position_add, name="secretary_position_add"),
url(r'^secretary/position/(?P<pk>\d+)/edit/$', views.PositionEdit.as_view(), name="secretary_position_edit"),
url(r'^secretary/position/(?P<pk>\d+)/delete/$', views.PositionDelete.as_view(), name="secretary_position_delete"),
url(r'^secretary/attendance/$', views.secretary_attendance, name="secretary_attendance"),
url(r'^secretary/attendance/attendance.csv/$', views.secretary_attendance_csv, name="secretary_attendance_csv"),
url(r'^secretary/brother/list/$', views.secretary_brother_list, name="secretary_brother_list"),
url(r'^secretary/agenda/$', views.secretary_agenda, name="secretary_agenda"),

could instead become:

url(r'^secretary/', include(secretary_patterns))

secretary patterns = [
url(r'^$', views.secretary, name="secretary"),
url(r'^positions/$', views.secretary_positions, name="secretary_positions"),
url(r'^positions/add/$', views.secretary_position_add, name="secretary_position_add"),
url(r'^position/(?P<pk>\d+)/edit/$', views.PositionEdit.as_view(), name="secretary_position_edit"),
url(r'^position/(?P<pk>\d+)/delete/$', views.PositionDelete.as_view(), name="secretary_position_delete"),
url(r'^attendance/$', views.secretary_attendance, name="secretary_attendance"),
url(r'^attendance/attendance.csv/$', views.secretary_attendance_csv, name="secretary_attendance_csv"),
url(r'^brother/list/$', views.secretary_brother_list, name="secretary_brother_list"),
url(r'^agenda/$', views.secretary_agenda, name="secretary_agenda"),
]
