## @brief this function implements a quicksort in place
# using the SchedulableQueue methods
#
# The compare parameter should be a user defined function
# name returning either True or False, defined like:
# @code
# def compare(SchedulableA,SchedulableB):
#     return SchedulableA.someProperty() < SchedulableB.someProperty()
# @endcode
#
# @param queue The SchedulableQueue to be sorted in place
# @param cmp The binary function to use to compare elements
# @returns None
def sort(queue, cmp):
    pass
