Importing and exporting soundings

Using the sounding export function, it is possible to export soundings in ASCII format for use in other applications. It is also useful to backup separate sounding files from a project, for instance to import them into another project or just for archiving.

The ASCII import function allows you to import soundings written in ASCII format.
For instance, to import a sounding exported from another Hydromagic project, or created with other software.
