Compressing files from Dyalog APL

This class is a wrapper that allows you to use 7zip from within Dyalog APL.

Warning

Note that 7zip issues an error when you pass something like this with the flag to preserve the directory structure:

C:\My\folder1\file.txt
C:\My\folder2\file.txt

This is clearly a bug. However, you can easily get around this by executing the command within C:\My and this list of files:

folder1\file.txt
folder2\file.txt

In other words, relative paths are fine, but absolute ones are not.

Since version 1.1.0 the SevenZip class issues in hint if this error occurs and absolute path names are used.
