Short helpfile for action KERNEL
****************************************

The following arguments are compulsory: 

                   TYPE - ( default=gaussian ) the type of kernel to use 
                 CENTER - the position of the center of the kernel 
                  COVAR - the covariance of the kernel 
                 WEIGHT - ( default=1.0 ) the weight to multiply this kernel function 
                          by 
                 NUMBER - ( default=1 ) if there are multiple sets of kernel 
                          parameters in the input file which set of kernel parameters would you 
                          like to read in here 

In addition you may use the following options: 

             NORMALIZED - ( default=off ) would you like the kernel function to be 
                          normalized 
                    ARG - the arguments that should be used as input to this method. 
                          You can use multiple instances of this keyword i.e. ARG1, ARG2, 
                          ARG3... 
                  SIGMA - square root of variance of the cluster 
              REFERENCE - the file from which to read the kernel parameters
