with d321e81f...d321e81f~3 developer support scripts were added

Obsolete branches were removed recently without intention. Some push command
apparently was issued with the --prune option, removing all branches which
existed only in the remote repository. All legacy branches are still
represented by tags - as they should be. No loss of data has occured. The
issue was resolved unintentionally.

issue#5 is resolved by commit 62436073

issue#6 is newly opened:
Application of the direct-wave transformation by lisousi is not reasonable. It
results in a division by zero. Make the program catch such cases and bail out
with an appropriate error message.

mission statement
-----------------

The branch whatscooking is an issue tracking facility kept along with the
Seitosh repository, but separate from the actual Seitosh commits. Commits to
this branch record open issues and suggestions for issue resolution. The
actual steps taken in order to resolve issues shall be recorded in commit
messges to the main Seitosh branches. The whatscooking branch is regarded as
unnecessary for operation of Seitosh and may vanish from the repository
at any instance.
