Determine the lower and upper endpoints of an alpha cut of a fuzzy cluster.
[inf,sup]=AlphaCut(x,U,v,range,CutLevel)
The cluster is given by points.

Parameters
-------------------------------------------------------------------------
x - Column vector containing the data points. It should
be sorted in ascending order.
U - Row vector containing one row of the membership
matrix that corresponds to the current cluster.
Each column represents a data point.
v - Center of the cluster.
range - Range of the current linguistic variable.
CutLevel - Indicates at which alpha level the shape of the
cluster should be cut.
-------------------------------------------------------------------------
Returned values
-------------------------------------------------------------------------
inf - Lower endpoint of the cut.
sup - Upper endpoint of the cut.
