    99== Overview == 
    10 Evaluate the current undo code with regard to PRO_LIB needs. 
     10The PRO_LIB needs to be able to track and undo/redo changes made to properties.  I believe these are called "auto properties"  You will need to write a module, or modify the existing undo manager, that can be used when auto properties are indeed changed. 
     11 
     12Grouping is also important, because changing one property may cascade and change 12 others.  This task needs to track this and make sure it is undoable. 
     13 
     14This task also needs to document the undo manager so that others use it properly. 
     15 
     16Also consider the need to merge change sets.  This would be applicable in, for example, a collaborative environment.  Whatever sets come out of the grouping requirement, determine if those change sets are able to be merged, or if this is an impossible task for now.

    16  * Ensure the ability to group changes 
    17  * Add the ability to merge change sets 
     21 * Add the ability to undo/redo auto property changes 
     22 * Add the ability to group changes 
     23 * Evaluate the ability to merge change sets
