3	info:~
4	Basic information about this simulation:
5	www.framsticks.com/foraminifera
6
7	Technical information:
8	Genes and parameter values which control reproduction are stored in user1 and user2 fields.
9
10	user1:
11	genes which are not encoded in Ff genotype:
12	min_repro_energy - Minimum energy necessary for reproduction
13	hibernation - Defines foram behavior in the case of no nutrients
14
15	user2:
16	Physiological parameters of foraminifera:
17	max_energy_level - maximum energy level reached so far
18	gen - generation: 0 haploid, 1 diploid
19	species - species: 0 not hibernating 1 hibernating
20	hibernated - 0/1 foram is/isn't hibernated
21	reproduce - 0/1 foram isn't/is ready for reproduction
