This is test program for fitting algorithms in Haskell. At the moment is implemented only line fitting with "Least Squares" algorithm. As UI is used Tcl/Tk (ran wish.exe interpreter), all commands are sending to Tcl/Tk interpreter and getting as lines back. Program works in Win32 but must works (after recompilation sure) in Linux/Mac too.
It's very simple implementation with some bugs - not all quadrants seems to work good. Also L.S. is simplest algorithm so there is some error on noise points.
