+
+// Phase 0 - This is driven by CDClassDump, registering types from all of the classes, categories, and protocols.
+// - This collects all the top level types (or struct/unions?), keeps a reference count, and flags any that were used in a method.
+// - If a top level struct was used in a method, then the type MUST be declared at the top.
+// - At the end of phase 0, these types are recursively visited, renaming structs whose name starts with $ (like $_12345) to ?, so
+// that we'll treat them as anonymous structures.
+// - Those names must be generated by the compiler. It can end up with different numbers for the same type.
+
+// Phase 1 - This goes through all the types collected in phase 0, and recursively registers each structure and union with the type controller.
+// - We are not concerned about reference counts or the isUsedInMethod flags.
+// - Since structures and unions can be nested in each other, we need to process each table before doing the end-of-phase work.
+// - We record the maximum structure depth.
+// - Since the deepest union may be buriend in a structure instead of referenced at the top level, we can't calculate the max depth from phase 0.
+// - On the other hand, since we're only interested in the max combined depth of structures and unions, the end result would be the same.
+// - The result of phase 1 is phase1_groupedByDepth: a dictionary keyed by the structure depth, containing arrays of CDStructureInfo.
+
+// Phase 2 - This is driven by CDTypeController.
+// - The goal of phase 2 is to gather member names and types (@"NSObject" vs just @).
+// - It goes through all of the phase1 groups, shallowest to deepest.
+// - For each level group:
+// - First it merges the results of all previous groups with the types at this depth.
+// - Then we group the CDStructureInfos, named structures by name, anon structures by reallyBareTypeString
+// - If they could be combined, the combined CDStructureInfo is to phase2_namedStructureInfo or phase2_anonStructureInfo.
+// - If they couldn't be combined, the uncombined CDStructureInfos are added to phase2_nameExceptions or phase2_anonExceptions.
+
+// Phase 3 - Using all of the information available from the merged types from phase 2, we merge these types with the types from phase 0
+// to fill in missing member names, and the occasional object type.
+
+// After all the phases are done, typedef names are generated for all anonymous structures, and then field names are added for missing fields.
+// - bitfields don't need to have a name, so they can be blank.
+// - the typedef name is calculated from a hash of the typeString.
+// - Doing it before adding missing fields means we could change the field names without changing the typedef name.
+// - Makes the name independant of the order they were encountered (like the previous indexes were). You can get meaningful diffs between
+// framework changes now.
