Pre-release version 0.97

• Looping behaviour : The module can now create loops in the forest road network, in order to account for more realistic fragmentation measures
• The module now takes into account the fact that if a repeated harvest (single or multiple repeat) is used on a cell, then a road will be needed to come back at the next rotation. Therefore, if road ageing is taken into account in the parameter file of the module, the module will then try to find the best (cheapest) option between creating a lower road type that will get destroyed before the next rotation (due to road ageing) and that will need to be re-constructed to access the harvested site again; or building a more solid, but more costly type of road that will last until the next harvest rotation.
• Fixed a bug concerning the wood fluxes that resulted in some incoherent road types.
