fix a bug in generating events from expected simultaneous pdf reported 
by Max Baak.  
 When using pdf.generate for simultaneous extended pdf with the binned option the number of expected events used to generate was truncated to an integer instead of being used as a double. 
This bug caused also to have also the case of zero events generated removed. 

A simila rounding was happening also  in case of pdf.generateBinned for extended single (not simultaneous) pdf.

Add a special case in the Merge method when the first histogram to merge is empty. 
In this case and when the histograms have different axis limits, the axis limits must be computed using the first non-empty histogram
