CMOS MERGE - Low-level methods to manipulate status flags

[pilotmm]

fused_data_set.py: MODIFICATION: The status data needs to have low-level methods to manipulate aswell. What if I only want to set job id 1 for example and leave the rest as 'unset'? Furthermore, the status flag can be stored as an int. However it is better that the interface has descriptive set/get methods like, has_data_been_set(name,jobid).
