Bugs

• The fuzzy comparison of floats is the source for all sorts of weirdness. If a result in R surprises you, try to run the program in Q before you send me a bug report.
• The projector for floundered nonlinear relations keeps too many variables. Its output is rather unreadable.
• Disequations are not projected properly.
• This list is probably incomplete.
