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

Cleaned example directory; field class created and working for CHIMERE (warning adj test not working yet); reading and re-indexing of values working

Added vertical dimension to control vector; adding generic field class to read fields to be interpolated at the control vector resolution and back to the model resolution

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

Removed *.a in CHIMERE; solved bugs due to new versions in Python; Save before modifying base classes
