Duplicate flowline points when using calibration

[oliverbobby]

When there is not a large difference between the flowlines of two different years duplicate flowline point can appear. Duplicate points show in flowline points that have used calibration points. It is not a duplication of every point. Some of the original points and calibration points are present in the final output.

After a discussion with Mike some sections of code were identified as potential sources for the point duplication.
The join field in lines 212-217 and the use of the Object_ID field. Discussed use of a spatial join. Also, Possible issues in line 207 with use of station_distance used for the radius_or_tolerance.
