# For every polygon in your input vector the script gets each line and prints the coordinates of each vertex, line distance and angle.
# Order of vertices listed are based on the line direction. Imagine drawing two identical squares in two different ways. 1) without lifting the pen and 2) draw one side, lift pen, start second line at start of 1st line, etc. ... The two squares will look the same but have different line directions.
# The 3squares vector in the SimplePolygons.rvc uses a line cartoscript to draw lines - the arrows indicating line direction
