+		- clusters are defined as high-density regions separated by low-density regions
+		- core points, border points and outliers
+			- outliers are not assigned a cluster and thrown away
+		- doesn't work very well if clusters have varying densities (low-density cluster could be assigned entirely as an outlier and removed)
