when dtmax is changed automatically could this be reflected in the filenames?

at the moment dtwallmax is set to 12 hours by default, meaning that if a simulation will not produce output in 12 hours then the snapshot frequency is increased in order to achieve this.

This is good but wholly confusing because the files keep the same names, i.e. disc_00001, disc_0002, disc_00003, disc_00004. So it is not at all clear to the user that the time interval between files has changed.

I would propose that we change the naming scheme when the dump interval is changed. One idea would just be to write "sub-dumps", e.g.

disc_00001
disc_00002
disc_00002_01
disc_00002_02
disc_00002_03
disc_00002_04
disc_00002_05
disc_00002_06
disc_00002_07
disc_00002_08
disc_00002_09
disc_00003

Not sure if this would be even more confusing, however, and would require some "memory" of what the original snapshot interval was. At the moment we just change dtmax and we are done and hence the files just keep adding 1 to the output.

Would something like the above be useful? Any better ideas here?
