1. get xyz+ file
2. remove points preceding 2006
3. calculate time to next point
4. calculate distance to next point
5. pass through the list
   1. assign ID 1 to the first point
   2. continue through the points. If there is a time break more than ?? seconds, assign ID 2+

      (Now we have a list of potential lines)

6. remove points with HDOP >= 8 and #SV < 4.
7. pass through the list again for each subset of points with the same ID
   1. assign ID.1 1 to the first point
   2. continue through the points. If there is a distance break more than ?? ft, assign ID.1 2+
8. Collect the point sets to create singlepart lines (for those points that have only 1 ID.1) and multipart lines (for those points that have multiple ID.1.
