The use of the term 'source' in the context of post-processing is confusing and does not properly describe the process of region selection. The new names 'surfaceRegion' and 'volRegion' better describe the purpose of the functionObjects which is to provide field processing functionality limited to a specified region of space, either a surface or volume. The keyword 'source' is renamed 'regionType' which better describes the purpose which is to specify the method by which the surface or volume region is selected. The keyword to select the name of the surface or volume region is renamed from 'sourceName' to 'name' consistent with the other name-changes above.
