A testing framework for the scons-time.py script
A TestSCons_time environment object is created via the usual invocation:
test = TestSCons_time()
TestSCons_time is a subclass of TestCommon, which is in turn is a subclass
of TestCmd), and hence has available all of the methods and attributes
from those classes, as well as any overridden or additional methods or
attributes defined in this subclass.
