Script to find the area of shapes in Adobe Illustrator

Illustrator/Presets/en_US/Scripts folder. You can then
access it from the File > Scripts menu */

Script grabbed from
https://gist.github.com/bryanbuchanan/11387501
fixes negative areas "bug" (some areas are shown negative)
and shows result in square milimeters, given that's
the default unit used in document.

I made it so you can show 2 dimension at once and adjsut the decimals and to show total or sepatate shape areas
