Program: MKLSGRIDEXTRACTLOCTRI

  mklsgridextractloctri........extract best fitting nodes from triangular grid
 
  call: loc=mklsgridextractloctri(lsopt,mygrid,level);
 
                lsopt: (struct)
                       LOCSMITH options structure as returned by MKLSOPT
               mygrid: (struct)
                       LOCSMITH search grid as returned by MKGRIDNEW
                level: (number) [counter]
                       All nodes are extracted that are compatible with
                       at least LEVEL data.
                       If LEVEL is the empty matrix [], LEVEL is set to the
                       maximum achieved compatibility internally.
 
 
  result: loc: (structure array)
 
               structure containing the nodes with maximum compatibility
               with the evaluated data. The structure contains the
               following fields:
                .type: (string)
                       grid type (from mygrid.type)
              .maxfit: (number) [counter]
                        the degree of compatibility of the returned nodes
                        (i.e. the number of data to which they are
                        compatible)
            .nodelist: (numeric array) [deg deg km]
                        List of 3D coordinates of nodes.
                        nodelist(i,1) is the node longitude, in deg
                        nodelist(i,2) is the node latitude, in deg
                        nodelist(i,3) is the node radius, in km
 
           .origintime: (structure) [sec]
                        list containing the origin time intervals for each
                        node, conatining the following fields:
                        
                        .id: node ID in the grid structure
                        .starts: start times of the origin time intervals
                        .ends: end times of the origin time intervals
 
                        the i-th node is a possible hypocenter in the
                        time intervals given by .origintime(i).starts and
                        .origintime(i).ends.
                        Not that ther might be more than one interval for
                        each node (unlikely, but possible)
 
            .nodecnt: (number) [counter]
                       The total number of nodes in MYGRID.
