mvsa: move-scan-analysis

The macro mvsa moves a motor to a peak position. The position is determined by analysing the most recent .fio file.

 
Syntax:
   mvsa <mode> <interactiveFlag> -> <result>

   Reads the most recent output file and moves a motor 
   to the maximum of the column defined by SignalCounter.

   Used environment variables: 
      ScanDir, ScanFile, ScanID  -> file name
      ScanHistory                -> motor name and scan type, 
                                    supported: ascan, a2scan, a3scan, dscan, d2scan, 
                                    d3scan, hscan, kscan, lscan, hklscan
      SignalCounter              -> counter name   
      'mvsa show' shows the results, no move 

   Parameters:
       mode : (String) Options: 'show','peak','cms','cen','dip','dipm',
              'dipc','slit', 'slitm', 'slitc', 'step','stepm' and 'stepc'
       interactiveFlag : (Integer)  '1' query before move (def.) 

    Result:
        result : (String) 'status=False' or 'status=True,mot1=12,...'
