+Step Input block :
+
+Step size is the height of step user wants to generate.
+Height of Offset is the height of step user wants to generate as initial signal.
+Width of Offset is the length upto which user wants to see the generated offset before starting with the height equivalent to step size.
+
+Default step size is 1 unit.  
+Default height and width of offset is 1 unit
