- Add swap() method signature to SchedulableQueue

- Export swap() to SWIG
- Add sort function (just its documentation, actually, implementation will
follow) to Policy.py

## @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

*
* At the present moment, this function shouldn't throw any
* exception, but just do nothing when the parameters don't
* make sense (e.g. positionB > this.size()).
* However, it should work the same either if positionA is greater
* than or less than positionB.
* In the future, this method could throw an OutOfRange exception.

* \param positionA The position of the first element to swap
* \param positionB The position of the second element to swap
