C FORMAT - sort/cmoname/bins/
C [ASCENDING|descending]/[ikey]/in_att/[epsilon_user]
C FORMAT - sort/cmoname/index|rank/
C [ASCENDING|descending]/[ikey]/in_att1 in_att2 in_att3 ...
C FORMAT - sort/cmoname/line_graph/
C [ASCENDING|descending]/[ikey]/lg_sort_type
C
C INPUT ARGUMENTS - imsgin,xmsgin,cmsgin,msgtyp,nwds
C TOKENS
C 1 sort
C 2 cmoname = name of MO to operate on ( / / and /-def/ supported)
C
C 3 index - multi-key sort such that in_att1(ikey(i)) i=1,...nnodes
C lists the attribute in_att1 in ascending or descending order.
C
C The ikey attribute will contain the permutation vector
C that could then be used in reordering the MO.
C (i.e. reorder/cmo/ikey)
C
C 3 rank - multi-key sort such that ikey(i) lists the ranking of the node
C in the sorted list.
C 3 bins - single-key sort which assigns each in_att1 value a bin.
C ikey(i) list the bin number of in_att1(i)
C If all array values are unique, then the maximum
C value of the index array will equal the number of
C entries in the sorted list. Otherwise, the
C maximum value of the index array will be less than
C the number of entries in the sorted list but will
C equal the number of unique entries in the list.
C
C When the bins option is used there is an optional
C argument, epsilon_user, that sets the epsilon value
C used to compare bins. Default is 1.e-10.
C
C 3 line_graph algorithm sorts elements or nodes
C default calls sort on elements
C
C 4 ascending - default, sort in ascending order
C
C 4 descending - sort in descending order
C
C 5 ikey - integer vector (VINT) which will hold the output
C sorted key values. If it exists it will be used,
C if it does not exist it will be created.
C If token is -def- the default key attribute name
C will be concatination of 'ikey_' and the first
C input attribute name. (i.e. /-def-/imt will produce
C a sort key named ikey_imt). If the line_graph option
C is used, and token is -def- the key_name name will
C be named 'lg_ikey_nodes' or 'lg_ikey_elements'
C
C
C 6 in_att - input attribute node based array upon which the
C sorting routine will sort
C
C Multi-key sorts can have an arbitrary number of input
C attributes. Attribute in_att1(n) has priority over
C in_att2(n) in breaking ties.
C
C
C 6 lg_sort_type (for line_graph) - character string which controls
C the key_name
C that will be created by the line_graph
C algorithm. Options are 'nodes' and 'elements'
C Default is elements
C
C Note: all attributes are put into a real*8 work array
C before being sent to the sort routine.
C
C Old Syntax still supported
C
C USAGE - sort/xyz/[INDEX|bins|rank]
C
C sort/xyz/index - sorts the x,y,z coordinates integer arrays
C i_index, J_index, k_index such that xic(i_index(i)) i=1,..nnodes
C lists the coordinate in ascending order.
C sort/xyz/bins - sorts the x,y,z coordinates and assigns each
C i_index, j_index, k_index values in ascending order of
C the bin number of the sorted list.
C sort/xyz/rank - sorts the x,y,z coordinates and assigns each
C i_index, j_index, k_index values the ranking of the
C node in the sorted list.
C
C If all array values are unique, then the maximum
C value of the index array will equal the number of
C entries in the sorted list. Otherwise, the
C maximum value of the index array will be less than
C the number of entries in the sorted list but will
C equal the number of unique entries in the list.
C
C For example given x = 0, 1, 2, 1, 0
c sort/xyz/index would return i_index = 5, 1, 4, 2, 3
C sort/xyz/bins would return i_index = 1, 2, 3, 2, 1
C sort/xyz/rank would return i_index = 2, 4, 5, 3, 1
C
C
C
C OUTPUT ARGUMENTS - creates 3 new node lenght vector integer attributes
C i_index, j_index, k_index.
C
C END OF Old Syntax still supported
