AssetModificationProcessor

assetOrMetaFilePaths contains either the asset.meta file (when clicking on imported files), or the asset file path (when clicking on unity assets).

assetOrMetaFilePaths never seems to contain more than one asset, even if multiple assets are selected. ^{[research needed]}

The function returns whether the inspector for this set of assets should be displayed. Returning false will disable the inspector.

I don't know what outNotEditablePaths does.^{[research needed]}
