This module provides data structures and routines for handling SAC binary files
in Fortran90. It provides a more object-orientated approach to handling SAC 
data. It currently only handles time series files. 

SAC file I/O can be achieved either with pure Fortran90 (negating the need for
a C compiler), or with mixed C and Fortran. The latter provides much better 
performance, but requires compatible compilers (for example, gfortran+gcc or ifort+icc). 

An example of use is given in 'test_f90sac', and the various compile time
options are documented in the Makefile. 

Please report any problems/bugs to the address above.
