Initial release
You should enter some logical values and the program calculate / solve the triangle.
You can enter 2 sides and 1 angle; 1 side and 2 angles; 3 sides.
The first field of angles can be used to transform between units a angle.
The app can fill some example values when click in the example triangles.
The app works in Gradians; Centesimal Degrees; Sexagesimal Degrees or Radians.
I just put a small ad at bottom, it do not disturb the user.
