[cmd] error in Kp-info

[Bioswinger]

Quick start guide notebook

Command used: pyntacle keyplayer kp-info -i AdvSeek.adjm -t dF --nodes HB,WD

error received: AttributeError: 'Namespace' object has no attribute 'nprocs'

[mazzalab]

this error was due to a missing parameter (--nprocs, -O) in the command line parser that, even if useless in this case, would have initialized the number of needed processes for this task to 1 (default choice). It was fixed.
