Random Snowflake Generator v11 ornament and earrings

This is a random snowflake generator using the free BlocksCad on-line educational system.
12.24.2017 update: now generates either ornaments or earrings:
- files with the word "earring" are sized for earrings
- files without the word "earring" are sized for ornaments
- BlocksCAD files are provided for both
- the BlocksCAD file random_snowflake_earring_2.xml has a small improvement that better positions the attachment loop

The image shows two examples of snowflakes generated by the program
