No HTML report is generated when using the parallel module

[unode]

This can be seen when running for instance the parallel test with ngless --create-report -o report parallel.ngl.

The reason is that generating the final HTML report would require collect()ing reports for each sample. This final step doesn't currently happen, even if only one sample is present in the samplefile.

Since this report would require aggregating several samples, its format also needs to be different from the single sample one.

This can be one of the goals of GSoC 2020 - Improved reporting of results project idea.

@unode Yeah, this can be a potential fix, and a potential Goal, I would be looking into this issue asap, and communicate the further details.

Wouldn't it be a possibility to just generate one html file pr sample with the sample name in the name of the html file. That was what I was expecting to get when I was using --create report for a script using the parallel module
