Remove a child library
You can remove a child library from a library if it is no longer required as a dependency.
To remove a child library from a library or product version, the parent of the library must be opened as the focus library in the Library Dependency Editor.
When you remove a child from a library, if this child library also
			has children, these children will also be removed.
 Note: When you remove
			a library, it is not deleted. It is simply removed as a child of the library. If other
			libraries in the dependency graph are also using this child library, the child library
			will not be removed from these libraries.
