Hi everyone 

I've been messing around with Graphene lately trying to run a private testnet. I've noticed that in the genesis.json there is the current_fees parameter that I guess contains all the fees paid for transactions, creating accounts etc etc. What I don't know is how to connect say:

          5,{
            "basic_fee": 500000,
            "premium_fee": 200000000,
            "price_per_kbyte": 100000
          }
with an actual operation? I can't seem to find it anywhere in the code... Any help would be appreciated
