A collection will generate a folder at the top level
The default level refers to the SDTF Token Type associated SD Category → {collectionName?}/{SDCategory}
The next folder level is the name of the potential first group containing the token → {collectionName?}/{SDCategory}/{1stLevelGroupName?}
The default filename is the name of the first group, or the name of the each mode the token might have, or base.json → {collectionName?}/{SDCategory}/{ mode? | 1stLevelGroupName? | base}.json (priority order for filename: groupName > mode > base)
The token path inside the file must match the token file path with the following priority order: collection > SDCategoryType > Mode > Groups
