The .pc (pkg-config) file content is inconsistent with include usage.

What I mean is that in the .pc you have : 
Cflags: -I${includedir}/m4ri -g -O2  -mmmx -msse -msse2 -msse3 -fopenmp

And then in m4ri.h you have :
#include <m4ri/XXX.h>

So either you need to :
 1) Expect the user to include <m4ri.h>, have  -I${includedir}/m4ri  in the .pc  and use #include <XXX.h> in your internal files.
or
 2) Expect the user to include <m4ri/m4ri.h>, have  -I${includedir}  in the .pc  and use #include <m4ri/XXX.h> in your internal files.

m4ri.pc.in should include $includedir with /m4ri at the end

m4ri.h expects the user to include ${includedir} but the pkg-config file suggests to include ${includedir}/m4ri which is inconsistent. It is better to include <m4ri/m4ri.h> to avoid conflicts if another project uses the same header filename as one of our headers.

This fixes #60
