[Haizea] sum operation in accounting module

[Mehdi Sheikhalishahi]

Hi,

How can I implement sum operation in accounting module? e.g. I want to add
data of all leases.
By defining a global variable it is possible, but I'd like to know whether
it is possible without it. And about stat we have set_stat in accounting but
not get_stat, if we have this method it would be possible this sum
operation.
