Renaming concepts around pages and frames
...
This commit renames `Frame` -> `UntypedFrame` and `Page` -> `Frame`.
So do other concepts in the following list:
- `Segment` -> `UntypedSegment`,
- `ContPages` -> `Segment`,
- `DynPage` -> `AnyFrame`,
- `PageMeta` -> `FrameMeta`,
- `FrameMeta` -> `UntypedMeta`.
This commit also re-organized the source in the `mm/page` and `mm/frame`
module to accommodate the changes.
