Calculate silhouette coefficient

• averageSilhouetteCoefficient(String nodeSet, String numberOfCentroid, String numberOfInteration, String distanceMeasure)

nodeSet :

used as condition for calculation

numberOfCentroid :

the number of desired clusters

numberOfInteration :

the number of optimal iterations (usually 100)

distanceMeasure :

• "euclidean"
• "manhattan"
• "cosine"
• "bray_curtis"

In the procedure mapped data from mapNodes procedure mapNodeList is used to perform averageSilhouetteCoefficient calculations.
