-
 Workspaces contain information in logs. Often these detail what happened to the sample during the experiment. This algorithm allows one named log to be entered. 
 
 The log can be either a String, a Number, or a Number Series. If you select Number Series, the current time will be used as the time of the log entry, and the number in the text used as the (only) value.

 /*WIKI*
 
+This is a workflow algorithm that does the bulk of the work for time focusing diffraction data. This is done by executing several sub-algorithms as listed below.

+# [[RemovePromptPulse]] (event workspace only)
+# [[CompressEvents]] (event workspace only)
+# [[CropWorkspace]]
+# [[MaskDetectors]]
+# [[Rebin]] or [[ResampleX] if not d-space binning
+# [[AlignDetectors]]
+# If LRef, minwl, or DIFCref are specified:
+## [[ConvertUnits]] to time-of-flight
+## [[UnwrapSNS]]
+## [[RemoveLowResTOF]]
+## [[ConvertUnits]] to d-spacing
+# [[Rebin]] if d-space binning
+# [[DiffractionFocussing]]
+# [[SortEvents]] (event workspace only)
+# [[EditInstrumentGeometry]] (if appropriate)
