Are there XTal datasets with more than one binding event

[Waztom]

@cvallee asks if there are xtal datasets with more than one binding event. This could be very useful for evaluating Creoptix fits where the model does not fit the data.

• Find datasets via Fragalysis
• Asses model/data fit
• Is there anything we can learn for signal assessment, specifically if the binding vent breaks the 1:1 assumption.
