fix for #21, image replacement

To achieve the above, you should navigate to the "Life Cycle Rules" tab and create a Creation Rule that will prevent the Metrico RFS from starting, unless the ```_MT_SERVICEUUID``` is provided. Also, you have to pass the updated user-defined Characteristics from the current to the Metrico RFS, when the previous condition is met. To do so, the rule has to be as the following:

Let's create it step-by-step:

- At the second slot, attach sequentially a) the Not and b) the String Comparison blocks (from Logic blocks)

- The Comparison block must compare the "consumingServiceId" variable value (From Text blocks) and an empty line of text (From Text blocks)

- At the final slot, attach the Create list block (from Lists blocks)

- From the last block's gear button, drag-and-drop more items in the list (must be 8, as the Characteristics)

- From the last block's gear button, drag-and-drop more items in the list (must be 6, as the Characteristics)

- At each list item, attach the Set values to characteristics of a referenced service block (Service > Relationships > Service Refs blocks)

- Each block must have the RFS's Characteristic Name (fill it in at a line of text block) and the respective Tvalue from the Get Value as String block (from Service > Characteristics blocks)

- Repeat for every characteristic, as shown above
