Users can define new variation filters to edit the variation json table defined in their scenes or completely define a new variation definition based on some user defined criteria.
A variation filter is a class with a "filter" method, the arguments are the following:
- variations: the current variation object. This is the current variation object and at this stage it might have been already edited by other variation filters
- atomsNode: the name of the atomsNode from your scene
- origin_data: the original variation string. You can get a variation object from this string using the Atoms.loadVariationFromString function.
