List of class references in FileSystemGs that need to be resolved

[dalehenrich]

This task/issue should be used to triage the disposition of each of the classes with separate tasks/issues for each of the classes that require significant work and or disucssion.

For each class we will decide to resolve the reference

• by eliminating code that references class
• replacing references with a GemStone equivalent
• porting the class from Pharo

When a decision is made as to how the reference is resolved, let's create an issue/task for that class with the planned resolution ... the issue will serve as the focal point for further discussion ... when the issue is resolved, we can check off the class
