SWIG/directors dependency removal (cont'd)

Removed all castToSomething() methods from Interface0D's subclasses.
These methods are useless, because introspection-based automatic type
conversion takes place whenever it is applicable.

If you need to rewrite old style modules that rely on the cast methods,
apply the following rewriting rules:

- SVertex.castToSVertex()
- TVertex.castToViewVertex()
- TVertex.castToTVertex()
- NonTVertex.castToViewVertex()
- NonTVertex.castToNonTVertex()

  These 5 methods return an object itself, so just removing a method
  call will suffice.  If you need to handle objects in a different way
  depending on their types, then you can use Python's type checking
  idioms such as "type(obj) is T" and "isinstance(obj, T)".  Example:

    [Original]
    v = it.getObject()
    # try to convert v into a TVertex object
    vertex = v.castToTVertex()
    if vertex != None:
	... # do something on the TVertex object
    # try to convert v into a NonTVertex object
    vertex = v.castToNonTVertex()
    if vertex != None:
	... # do something on the NonTVertex object

    [Rewritten]
    vertex = it.getObject()
    if type(vertex) is TVertex:
	... # do something on the TVertex object
    elif type(vertex) is NonTVertex:
	... # do something on the NonTVertex object

- SVertex.castToViewVertex()
- SVertex.castToTVertex()
- SVertex.castToNonTVertex()

  Use SVertex.viewvertex() instead.  You don't need to care about
  which cast method is appropriate.  SVertex.viewvertex() does, if
  necessary, introspection-based automatic type conversion for you.

- NonTVertex.castToSVertex()

  Use NonTVertex.svertex() instead.

- CurvePoint.castToSVertex()

  Let cp be a CurvePoint object, then this method can be expressed as
  follows:

    if cp.t2d() == 0.0:
	return cp.A() # returns an SVertex
    elif cp.t2d() == 1.0:
	return cp.B() # returns an SVertex
    return None

- CurvePoint.castToViewVertex()
- CurvePoint.castToTVertex()
- CurvePoint.castToNonVertex()

  Similarly, these 3 methods can be expressed as follows:

    if cp.t2d() == 0.0:
	return cp.A().viewvertex()
    elif cp.t2d() == 1.0:
	return cp.B().viewvertex()
    return None
