 +===== Input =====
 +TODO
 +
 +===== Output =====
 +In the results csv files:
 +
 +  * ''vol'' - "volumes": Mm³ (at the end of the year)
 +  * `forArea` - "area": ha (at the end of the year)
 +  * `regArea` - "regeneration area": ha
 +  * `vReg` - "regeneration area": ha
 +  * `vMort` - yearly death volumes:  Mm³
 +  * `hV`  - "harvested volumes": Mm³ (assumed at the beginning of the year)
 +  * `hr`  - "harvested rate": ratio
 +  * `harvestedArea` - "harvested area": ha
 +  * `hProductivity`
 +  * `expReturns` - "expected returns": €/ha
 +  * `sumExpReturns`
 +  * `pol_fiSub` - Rate of subsides to forest investments: rate: [0,1[ → subside; 1 → no intervention; ]1,+inf[ → tax
 +  * `polBal_fiSub` - Amount of subsides to forest investments: M€
 +

 +*  Some importan notes:
 +*    V (volumes)    -> at the end of the year
 +*    In (inventary) -> at the beginning of the year
 +*    Area           -> at the end of the year
 +*    Harvesting     -> at the beginning of the year
 +*    Volumes are in Mm^3, Areas in the model in Ha (10000 m^2), in the layers in m^2, vHa in m^3/ha. Prices are in €/m^3.
 +*    Policy balances (- -> public cost,subside; + -> public revenue) and surpluses are in milion €
 +*
 +*    BALANCE:
 +*    PROD_forLocal (sl) + PROD_forExp (sa) + IMP (da) + sum_reg(reg_trade_in) = CONS_fromLocal (dl) + CONS_fromImp (da) + EXP (sa) + sum_reg(reg_trade_out)
 +*    note that this means that sl includes alread reg_trade_out, and dl includes already reg_trade_in
