Options
Here are the options for the transform:
-  transform name : the name of the transform, needs to be unique in a pipeline 
-  Result field: the name of the output field, the sequence 
-  Start at value: the number to start at each time 
-  Increment by: the value to increase at each row in the same group 
-  Init sequence if value of following fields change: you can specify a list of fields here. If a value in one or more of these fields changes compared to the previous rows, the sequence will be reset to the start value.
