more general cluster commands introduced

1%'cluster_command': creates the command string for launching jobs in the cluster
3% function cmd=cluster_command(ListProcess,ActionFullName,DirLog,NbProcess, NbCore,CPUTimeProcess)
6% cmd=system command (char string) to launch jobs
10% ListProcessFile: name of the file containing the list of processes to perform
11% ActionFullName: name given to the action (function activated by series)
12% DirLog: name of the folder used to store the log files from calculations
13% NbProcess: number of processes in the list, these processed are grouped by the systwm into jobs dipatched to NbCore cores
14% NbCore: number of computer cores to which the processes are dispatched
15% CPUTimeProcess: estimated CPU time for an individual process (in min)
