Updated the create_dataframe and added function called variables, which tries to decide which variables to plot in parametric study and q scans. Works good for primary variable (usually om), and reduces the secondary (slice variable, temperature, mag.field,...) variables to a few candidates from which one has to be picked. In one set for param study, it identified all parameters correctly, in q scan, the temperature varied as well as H index, so technically both could be used, but only one makes sense and that will have to be picked by user.
Added one more parameter "variable", so we can use the function also for other scans than omega, will be necessary in param study and should not influence the ccl integration hopefully.
This is first idea how the function could work. Use should be the same as previous one but we need to find a way how to pass parameters to the function. There is a new parameter called variable, which should choose the x coordinate, since "om" might not be the only axis here. Function does not change the initial dictionary yet, but process will be the same as in the first one. It is still not clear how the peaks should be reported, more so what to report in case of two overlapping peaks (same goes for numerical integration), but the process will be similar to the fitvol2. The function can be used, but is posted here for a reason of discussion and finding the best way of passing the parameters.
