Trying to improve the occupation memory when computing GMFs
Small refactoring of compute_gmf_cache: now the test pass
Improved the test by using 5 sites x 2 ruptures
Small cleanup
Introduced the per_site dictionaries
Changed to use a single dictionary gmvs_per_site
Reverted to the situation with two dictionaries
Merged from fix-blocksize-conservative
Since we are using little memory, we can raise the BLOCK_SIZE
Merge branch 'master' of github.com:gem/oq-engine into improve-memory-gmf
A small fix
Merge pull request #1290 from gem/improve-memory-gmf

Improve memory consumption in the GMF calculation
