This function associates the landmarks with the observations.

Parameters

landmarks	Landmarks in the form of [x1, y1, x2, y2, ...] in the global frame
observations	Observations in the form of [x1, y1, x2, y2, ...] in the global frame
covariance	Covariance matrix of the landmark vector
observation_confidences	Confidence in the observations in the same order as the observations

Returns: Eigen::VectorXi Each entry corresponds to an observation and contains the index of the landmark that the observation is associated with in the landmark vector (x coordinate). If the observation is considered new, the entry is -1. If the observation is considered an outlier, the entry is -2.
