Mcpp style

### small changes
* ignore .npy  files
* removed some standard out from JsonParsing

### implement array ids from storage-dict
* change options --file-setup to --mc-old-setup , because these need further specification in user/mc_old_setup.py. This has been implemented for both make_plots.py and point.py
* introduce --storage-dict , which takes a json file contianing [(oid1,oid2,array_id), ... ] . 
* made the initialisation of axes dependent on the required axes to make the spaces.
* implemented function that populates a dictionary with array ids if the style is present, whereas it return None if it doesn't. 
* implemented some mcpp observable ids
* added a "get" function to user/mc_old_setup.py
