Boscoin rewards calculator
Calculates expected number of rewards by operating a BOScoin node.
Note that this is speculation, since we don't know how many frozen units/nodes
will be until genesis. Also note that this script is not applying increasing
number of total supply. However, roughly saying, rewards will not be changed
while every node operators, frozen coin holders try to reinvest all their rewards.
Becasue rewards are distributed by shares.
