a little warning

[soundsbeard]

first of all thank you for such great tool.
I was looking for a cross-platform tool to calculate the exact volume of stl when almost every piece of software provides only dimensions and weight.
I put 250mb file and my computer was dead for a while.
and the consequences were not so clear to me :)
so could you please add a little warning about the file size to the description?
the best thing would be if you could restrict memory/cpu usage, or add a message that "yout pc will be dead for 7 mins :D" but I suppose its not an easy task.
anyway thank you for this script!

250mb STL is a huge file. If you want send me push request with the warning if file is bigger 25mb: "your computer might take some minutes to calculated"
