Allow the users to change the compression rate of datasets.

Compression is switched off by default for performance.

Branch can be removed. Note also that there are no changes to the parallel_io routines as compression is not available with parallel hdf5.

Doesn't compile for me. I get:

serial_io.c: In function ‘prepareArray’:
serial_io.c:227:6: error: ‘e’ undeclared (first use in this function)
   if(e->snapshotCompression > 0) {
      ^

Added 1 commit:

• c257ba94 - Missing parameter in prepareArray().

Aarghhh. Sorry... I always have troubles compiling that version.

Thanks, looks good to go. Accepting.

Status changed to merged
