Test: expect weights from get_calcs
Return weights from get_calcs()
Test: move calc element retrieval to setUp()
Add test for calc_values

Function should return a list of lists of calculation inconsistencies
formatted like so:
[[link_role, total_elem, context, value, calculated_total], ...]
Add calc_values()

Function returns list of lists of calculation inconsistencies formatted
like so:
[[link_role, total_elem, context, value, calculated_total], ...]
Add test for insert_labels()

Add test for xbrl.insert_labels(), which accepts a calculation
inconsistency log from xbrl.calc_values() and inserts the standard label
for each total element.
Add xbrl.insert_labels()

Function accepts a list of lists of calculation inconsistencies (such as
from xbrl.calc_values) and inserts the standard labels of the total
elements.
Add test for xbrl.link_role_def()

Function should accept a schema and role URI and return the link role
definition.
Add xbrl.link_role_def()

Function takes a schema and link role URI and returns the link role
definition.
