SuiteSparse v4.5.3

SuiteSparse v4.5.3, May 4, 2016.

* minor changes to Makefiles

4.5.2:

* licensing simplified (no other change); refer to PACKAGE/Doc/License.txt
    for the license for each package.

4.5.1:

* update to Makefiles.  Version 4.5.0 is broken on the Mac.
    That version also compiles *.so libraries on Linux with
    underlinked dependencies to other libraries in SuiteSparse.
    For example, AMD requires SuiteSparse_config.  The links to
    required libraries are now explicitly included in each library,
    in SuiteSparse 4.5.1.
* minor change to CHOLMOD/Check/cholmod_write.c, when compiling with
    options that disable specific modules
