template: commu?clnt=<name|pass>&com=mkftrgrp&algorithm=clustermining&th=<num>&params=<param1|param2|..>
descript: Creates new clusters of features. The algorithm parameter is the algorithm that will be used for the clustering.
	  The params takes the needed parameters for the algorithm and must be seperated by the chaacter |.
	  Final the exclude defines the features that will be not given aw input to the cluster algorithm. If there are more than
	  one features that must be excluded the character | is used.The th is the threashold that distances must pass to create the binarized graph
example : commu?clnt=name|pass&com=mkftrgrp&algorithm=bk&params=0&exclude=ftr1|ftr2
returns : 200 OK, 401 (fail, request error), 501 (fail, server error)
200 OK  : no response body exists.
