Creates a locator object in the scene. A locator is a small icon like an x-y-z axis that marks a point in space. They are useful as a user interface for characters; for example, you can parent joints to the locator so moving the locator pushes and pulls the joint.
An attribute on the locator shape node allows you to change the locator’s local scale; that is, you can change the size of the locator (without affecting any objects that are parented or constrained to the locator).
