Fixed bug in LMDZ when dealing with initial conditions in fwd and adj; adjoint test succeeds for several consecutive months

Fixed LBC in CHIMERE adjoint (number of species + scaling factor vs physical factor); dealing with physical/scaling factors in control vector

Dummy model accepts observations spanning several periods; Hourly fluxes accepted; Removed data for dummy; Random data generated by CIF classes

Changed requirements; added class platform to deal with module loads and other platform specific commands; coding write flux for CHIMERE
