this dataset gives memroy problems, we will replace it with  more efficient way of storing the KG matrix

rename *PlatForm to *Platform

renamed class names Ct- to CO2-
changed class name Observation to Observations 
small cleanup changes to template.py

in sv.write_to_file modified the prior/optimized identifier in function call to be prior/opt text instead of True/False

changed the function calls in order to remove need of sth.DaCycle = DaCycle in start_job. achieved by adding DaCycle to particular function calls and initializing tm5 with DaCycle as call parameter

added the get_covariance generic function to the sv baseclass

write_members_to_file: is called with _lag_ instead of lag +1, as inside there was a "lag-1" call... that one removed from inside as well

write_sample_info changed to take the whole path as a parameter: so now we explicitly see the path in pipeline, plus we don't need to return it back.
same for write_obs_to_file

managed imports in obs files

removed a need of using samples.DaCycle=DaCycle (now it is only passed in the "initialize" function)

removed StateVector.isOptimized and replaced with an "optimized" parameter in StateVector.write_to_file call

in obs and obspack_geocarbon adding some parameters to function calls

removed "oldstyle" and "newstyle" checkings from write_obs_to_file (it was added for debugging purposes at some point...)

Changed expand_mixingratios to allow R and HPHR to be either matrix or vector depending on algorithm choice (serial or bulk).
