def makeFountainPark(wxd, treeShaders, daytime, lightGeom):
'''
Creates a park with a fountain in the middle.
wxd: A tuple containing the width and the depth of the park.
treeShaders: A list of shaders for the tree crowns.
daytime: Boolean variable which is true if it is day and false if it is night.
lightGeom: Tuple containing the object name and node name for a polygonal object,
in this case a street light.
On exit: A park with trees (placeTreesInSquare(...)), fences (makeFence(...))
and street lights (trafficLight.placeLight(...)) has been created and
a fountain has been created in the middle of the park using
makeFountain(...). Everything has been combined into a single polygonal
object except the lights, which are instead parented to this object.
The park object is returned as a tuple containing the object name and
node name.
