expdef:
name:Reproduction of benthic foraminifera
info:~
Basic information about this simulation:
www.framsticks.com/foraminifera

Technical information:
Genes and parameter values which control reproduction are stored in data->genes and data->lifeparams fields.

genes:
genes which are not encoded in Ff genotype:
min_repro_energy - Minimum energy necessary for reproduction
hibernation - Defines foram behavior in the case of no nutrients

lifeparams:
Physiological parameters of foraminifera:
max_energy_level - maximum energy level reached so far
gen - generation: 0 haploid, 1 diploid
species - species: 0 not hibernating 1 hibernating
hibernated - 0/1 foram is/isn't hibernated
reproduce - 0/1 foram isn't/is ready for reproduction
