"""\
ThanCad 0.0.9 "DoesSomething": 2dimensional CAD with raster support for engineers.
This module maintains currently opened files and recent files.
A ThanCad project is a triad of:
1. Absolute path name where the drawing is stored.
2. The drawing object which holds the drawing in memory.
3. The window where the drawing is shown on.
The 2,3 are unique for each project. Absolute path name should also
be unique (i.e. same absolute path name mean exactly the same projects).
But, of course, if someone mounts a filesystem in between, the same
pathname might point to a different project.
ThanCad may have 2 opened projects with the same pathname simultaneously
because 2,3 will be different.
ThanCad will maintain unique pathnames (not filenames) in recent files.
