public abstract class DataSelectorCreator
extends java.lang.Object

Something that creates data selectors. It also keeps a list of available data selectors, which are each named with a string so when asked for one, will be able to either give the existing one, or will create a new one.
In this way, it's possible for multiple objects to use the same data selector, but DataBlocks that use these things should create separate settings for each so that different parts of the system can work with different selections.

Finally, these things can also keep a central register of all data selectors, so that their settings can get serialised when settings are saved.
