New issue 318: Create Angle of Line user function https://bitbucket.org/valentinateam/valentina/issue/318/create-angle-of-line-user-function
Susan Spencer:
Create a function angleOfLine(A, B) which returns the angle in degrees of the line from A to B. The angle of line is always positive, 0 <= angle < 360
The user can use this function anywhere an angle is required.
