Moved holiday buttons to an include to share code.
Added the get_subordinate function - now to introduce it.
Try/Catch and some extra logic about inserting the super into their own queryset.
More tests.
Employ the get_subordinate function in the gen_holiday_page function.
More conditional changes to use the model's interface rather than the straight field comparisons.
get_subordinate uses a single conditional for sup/admin/tl users rather than splitting between sup/admin and TL.
Added more tests
Typo fix
Merge branch 'get_subordinate'
Merge branch 'include_holiday_buttons'
