说明： in the social sciences, is a group of individuals who interact with one another and share similar interests.[1] Interacting with cliques is part of normative social development regardless of gender, ethnicity or popularity. Although cliques are most commonly studied during adolescence and middle childhood development, they exist in all age groups. Typically, people in a clique will not have a complete open friend group, and can therefore "ban" members of the clique if they do something that is considered unacceptable, such as talking to someone generally disliked by the clique. People who are part of a clique are bonded together through shared and similar social characteristics such as race, ethnicity, economic status and physical appearance

##OPTICS CLUSTERING##
This MATLAB function computes a set of clusters based on the algorithm introduced in Figure 19 of Ankerst, Mihael, et al. "OPTICS: ordering points to identify the clustering structure." ACM Sigmod Record. Vol. 28. No. 2. ACM, 1999.

**Input:**
points - input points to cluster where each point is a separate row and the columns are data dimensions
minpts - the minimum points required to form a cluster
epsilon - a percentage threshold to make a cluster
**Output:**
SetOfClusters - a struct containing each cluster's start and end index
RD - each point's reachability distance
CD - each point's core distance
order - the order of points in the reachability graph
**Dependencies:**
This function requires optics.m from Michal Daszykowski's implementation of calculating the reachability distance for all points.
