"""
Test function that assigns a quality value [0...4] to a pick uncertainty.
The pick uncertainty is compared to the error classes.
A pick uncertainty that is below the first error class is assigned the best quality, quality 0.
A pick uncertainty that is above the first error class but below the second is assigned quality 1 and so on.
A pick uncertainty that is larger than the biggest error class is assigned quality 4.
The upper border of a quality class is inclusive, the lower border exclusive. Meaning if a value is exactly on the
border between two classes, it is assigned into the higher quality class (represented by the lower number).
