in contrast to other smalltalks, ST/X does not keep the
method <-> category associations in the class (as organization),
but instead keeps the category as an instance variable of methods.
For compatibility with (fileOut-) files which include a class organization
message, 'aClass organization' returns an instance of this class, which
implements the category change functionality.
Also, some PD code seems to use & define methods for ClassOrganizers
- having this (somewhat dummy) class around helps to fileIn that code.
Notice, that instances of ClassOrganizer are NOT used in the current ST/X
system; all of this is pure compatibility mimicri.
This is an additional goody class; therefore:
