title: Making a list of streetadresses
body: <p>SOLVED :-)
  I'm having this list, and would like to get the expected result, but no luck.
  Tried in python and FME</p>
  
  <p>If there is more than 2 between the current and then previous number, a new line has to start</p>
  
  <p>Can anybody help? Preferable in FME, but okay in python too</p>
  
  <pre><code>StreetName;HouseNumber;OddEven
  Northroad;1;O
  Northroad;2;E
  Northroad;3;O
  Northroad;4;E
  Northroad;8;E
  Northroad;10;E
  Southroad;1;O
  Southroad;2;E
  Southroad;3;O
  Southroad;4;E
  Southroad;10;E
  Southroad;12;E
  Southroad;14;E
  </code></pre>
  
  <p>My result:</p>
  
  <pre><code>Northroad 1-3
  Northroad 2-10
  Southroad 1-3
  Southroad 2-14
  </code></pre>
  
  <p>Expected result:</p>
  
  <pre><code>Northroad 1-3
  Northroad 2-4
  Northroad 8-10
  Southroad 1-3
  Southroad 2-4
  Southroad 10-14
  </code></pre>
  
  <p>Does it make any sense?</p>
