io.mmread in CVS is now about 4.5 times faster and supports also reading
.mtx.gz files (though gunzip'ig such files in harddisk makes 
io.mmread faster). io.mmread is still pure Python and implementing it in C 
should give more speed at the cost of being more strict to io.mmread 
argument, e.g. reading .mtx.gz would have to happen in pure Python.
