- Vertex detection bug fixed.
- Input methods prevent a new line from duplicating.
- Degradation of estimation button is fixed. It would not show error messages.
- Speed up: finding the nearest vertex, pasting lines and adding line. Maybe it won't hang up now. (but slow in a test with 100*100 grid data.)
- Some bugs are fixed.
