Functions
int	flag_stgy_init_auto (Flag *flag_stgy)
	Set the flag to automatic paramaters.
int	flag_stgy_init_zeros (Flag *flag_stgy)
	Set the flag parameters to zeros. This is almost the same as automatic.
int	flag_stgy_init_defined (Flag *flag_stgy)
	Set the parameters flag to the defined ones.
int	print_flag_stgy_init (Flag flag_stgy)
	Print the flag parameters values.

Revision 1.0b 2012/05/07 Frederic Dauvergne (APC) Official release 1.0beta. The first installement of the library is the Toeplitz algebra module.

Revision 1.1b 2012/07/- Frederic Dauvergne (APC)

• mpi_stbmm allows now rowi-wise order per process datas and no-blocking communications.
• OMP improvment for optimal cpu time.
• bug fixed for OMP in the stmm_basic routine.
• distcorrmin is used to communicate only lambda-1 datas when it is needed.
• new reshaping routines using transformation functions in stmm. Thus, only one copy at most is needed.
• tpltz_init improvement using define_nfft and define_blocksize routines.
• add Block struture to define each Toeplitz block.
• add Flag structure and preprocessing parameters to define the computational strategy. All the flag parameters are then available directly from the API.

Revision 1.2b 2012/11/30 Frederic Dauvergne (APC)

• extend the mpi product routine to rowwise order data distribution. This is now allowing tree kinds of distribution.
• add int64 for some variables to extend the global volume of data you can use.
• Openmp improvments.
• Add toeplitz_wizard.c, which contains a set of easy to use routines with defined structures.
