WIP ENH: Add "limit" argument to dijkstra
TST: remove all docstrings from test functions for stats.morestats
BUG: runtests: chdir away from root when running tests

This makes it possible for subprocesses possibly launched by the test to
import the module under testing.

Also, do not pass --debug to setup.py build, since this can make the
build require Python debug symbols to be installed (on windows).
