Welcome, traveller!

Here's your task for today --

- You are given a .shapes file format. Each line in this file represents a shape in an image.
- A shape can be a square, a rect, a circle, an ellipse, a line, polyline and polygon.
- Each shape has different arguments, the last argument is the color in which to paint (#rrggbb). See sample file below.
- There are no empty lines in this file, and list of shapes end when file ends.

Shapes and formats:
- sq <X> <Y> <STRIDE> <COLOR>                   # square
- rt <X> <Y> <WIDTH> <HEIGHT> <COLOR>           # rect
- cl <X> <Y> <DIAMETER> <COLOR>                 # circle
- ln <X0> <Y0> <X1> <Y1> <COLOR>                # line
- pl <X0> <Y0> <X1> <Y1> ... <Xn> <Yn> <COLOR>  # polyline

You need to write a tool, that when executed as `php main.php input.shapes output.svg` will:
1. Create an svg file that represents these shapes, saved to disk.
2. Print out the sum of lengths of all shapes (length or circumference when applicable) 

Take into consideration these points:
1. How easy will it be to add more shapes in the future?
2. How easy will it be to change output to be a png?

What we'd like to see:
1. Working software :)
2. Clean code and proper classes
3. Design patterns in use
4. Code-review (done together)

Good luck!
We're here for questions and help!
Enjoy the time and music.
