Change of csv export. #91

Closed Ott-Alexander closed 7 years ago

Ott-Alexander commented 7 years ago

In this PR:

added a menu option export with the csv export.
changed the csv export to work on basis of the NDArray instead of QTableview.
added support for the export of 3d data.
changed the way the selection based export works to fit with the switch to NDArray

just noticed, when exporting large datasets, getting the headers takes at least half of the export time, and there is no update of the progress bar during that time. The application appears frozen.

If data is exported directly the header is always empty.

yet another thing I came across ;) When opening a large dataset in the table view, selecting a small subset (say 100 values) and exporting this selection the full headers are requested and the export takes a very long time...
