chessproblem.ui 1.2.0

This package contains the chess-problem-editor application and

some utilities around editing chess problems. The intention of this application is to have a visual editor application for chess problems written using the LaTeX-style named chess-problem-diagrams (diagram.sty).

There is also an application to maintain a simple author-database (the authors of the chess problems), so one may select authors from this database when entering new problems.
