removed potential memory leak

- memory on the heap is better managed now, deleting those pointers in the destructor
mayor issue resolved, subfolder structure

- the subfolder structure is read and dublicated in the /results/ folder
- ROOT files are written accordingly
- Analysis class therefore has new members _OutTemp, OutVolt, OutSample_ID plus according methods
mayor change

- changes single folder analysis to many folder analysis
-- read complete substructure with two subfolders (e.g. temp/volt/)
-- create subfodler structure in results
- created nested loop: loop over subdirs, then inside loop over acqs in that folder
- cleam up
- memory management at the end of loop
