 This is a library plus a test harness for collecting algorithms that use the
 GraphBLAS.  It contains the following files and folders:

-TODO, SPEC: all enum values in the spec should be defined.  They are not, so as
-a result, a user code cannot be linked against an arbitrary GraphBLAS library
-after it is compiled.  It must be linked with the same GraphBLAS library it is
-compiled with.  SuiteSparse:GraphBLAS defines all user-visible enum values
-explicitly.  See the SuiteSparse/Include/GraphBLAS.h.   Note that I have
-added a GxB_DEFAULT = 0 to the descriptor enum, GrB_Desc_Value (otherwise,
-there is no way to set a descriptor value to its default value).  Otherwise,
-I have numbered them in the order they appear in the tables in the spec,
-starting with zero.

 TODO: the following methods require GxB_Matrix_type:
 ./Source/Utility/LAGraph_ispattern.c
 ./Source/Utility/LAGraph_mmwrite.c
 ./Source/Utility/LAGraph_isequal.c
 (this needs to be added to the GraphBLAS API Specification)

-TODO: write an LAGraph_eWiseAdd (C,M,accum,A,B,op,amissing,bmissing,desc)
-that does eWiseAdd on the intersection only;
-for entries in A but not B, uses cij = op(aij,bmissing)
-for entries in B but not A, uses cij = op(amissing,bij)
