This is a fork of csgjs-cpp. The differences between this fork and the original version are:

• This fork uses double instead of float.
• This fork separates header and source files.
• The only field of vertex struct is pos.
• The functions union, intersection and difference renamed to get_xxx.
• Some geometric calculations are planned to be added.
