Returns a list with the Quebec Landscape Dynamic Model parameters and the default values

1	default.params()

A list with the following items:

year.ini: The inital year YYYY of the simulations
time.step: Time step in years (default value is 1)
duration.last.outbreak: String to indicate the unit of timber supply calculation
current.duration: A flag to indicate the systematic forestation of conifer communities that become broadleaves communities following a perturbation
collapse: Number of years of the current collapse phase. If 0 the phase is not activated yet
calm: Number of years of the current calm phase. If 0 the phase is not activated yet
preoutbreak: Number of years of the current preoutbreak phase. If 0 the phase is not activated yet
niche.opt: Weight of the optimal niche for sbw
niche.good: Weight of the good niche for sbw
niche.poor: Weight of the poor niche for sbw
enable.succ: A flag to enable natural succession every 40 years (if FLASE, composition remains the same)
enfeuil: After clear-cut, for a percentage of conifer species (EPN and SAB), transform to pionner species (PET)
age.seed: Below this stand age, seed production is very low, and regeneration failures are more likely
p.failure: Probability of regeneration failure in young (< 50 years) burned stands ([0,1])
suboptimal: Tolerance for sub optimal conditions ([0,1])
