Release Notes: This release adds a higher level API; maps can now be generated using expressions like "e200/s400/w200/n400", which would make a 400 x 200 rectangle. The usage examples are moved into separate files.
Release Notes: Shorts are no longer decoded as unsigned values. DOOM primitive wrappers (i.e. Linedefs and Sidedefs) are in place and can be used to make valid wad files.
