Removing extra factory functions.

The same result can now be obtained by passing a default GU_DetailHandle to the normal factory funtion
Making SOP factory function private.

This one is just for the bindings really. Keeping it on the class for now to avoid annoying friendships
Added name parameter to ToHoudiniGeometryConverter.

The blindData name is used for backwards compatibility only, and will be ignored if a name is provided through the parameter.

The Group converter uses blindData childNames on the Groups to name its children in the hierarchy, and in that case, the name parameter can be used to override the top level name only.
FromHoudiniGeometryConverters no longer add the name blindData.

We don't worry about backwards compatibility here, since we're coming out of Houdini and making new Cortex objects.

FromHoudiniGroupConverter does add childNames blindData to the Groups, so that hierarchical names will be maintained.

Also reorganized FromHoudiniGeometryConverter parameters to match order in ToHoudiniGeometryConverter.
Adding static utility function to extract a named bit of geo.
Adding nameFilter arg to python factory function.

This allows python users to convert partial bits of a GU_Detail based on names. It supports Houdini style match syntax.
Fixing SceneCache SOP for name changes.

No longer setting the blindData, and instead using the ToHoudiniGeometryConverter name parameter.
Updating HoudiniScene::readObject for name changes.

Now that we can extract the named bit of geo before converting, we can avoid the unnecessary conversion and search through the group.
Removing any use of childName blindData.

Undoing childNames blindData hack. From/ToHoudiniGroupConverters now add name blindData to their children when appropriate. None of the other converters deal with name blindData.
