Labelled data associations always used #20
Description
I noticed an issue where the labels on observations were always used regardless of the whether a labelled association type was used.
The problem is due to an error in condition logic which is present four times in multitracker.h. The condition is written as:
if (alg == NNJPDA || NNJPDA_LABELED)
Which always succeeds since NNJPDA_LABELED will evaluate to true. The lines should read:
if (alg == NNJPDA || alg == NNJPDA_LABELED)
