Fix multiple sensor file

[aremazeilles]

Fix #27

[alfonsotecnalia]

For the moment, it seems fine. Is it still a WIP?

[aremazeilles]

I think it is ok. What I don´t like, is that then, from the filename, we don´t know whether a file contain a single, or multiple information. But Let´s start with it....

[alfonsotecnalia]

In #27, I proposed this: 'name of the file: subject_N_run_R_wrench_tagOrID if we have files from different sensors and subject_N_run_R_wrench if only one file containing the info of all the sensors.'

This way you could differentiate.

This is what I wrote in the file, but I assume we make such distinction only if the tesbed uses several force sensors. If you have a single force sensor in the experimentation, then I would not put a tag in addition to the label "wrench".

But then, given a [...]_wrench file, you don´t know if it contains a single sensor reading (because the testbed only involves one), or several (because the testbed involves several sensors, and we decided to place all in a single file).

If we find interesting to differentiate without opening then we should propose to add tag

Let´s keep it as is, and keep in mind that possible adjustment if we see we need it...
