name:Reproduction of benthic foraminifera
info:~
Genes and parameter values which control reproduction are stored in user1 and user2 fields.

user1:
genes which are not encoded in Ff genotype:
Vamin - Minimum stored energy necessary for reproduction
amin - minimal age for reproduction

user2:
Physiological parameters of foraminifera:
Va - amount of the stored energy
gen - generation: 0 haploid, 1 diploid

/*
changes 2015-06-24:
- xxx.get(...) changed to xxx[...]
- xxx.set(...,...) changed to xxx[...]=...
- function placeRandomlyNotColliding(cr) explicitly called when adding a new creature, and removed collision checking from onCreaturesBorn() which is also called when "growing" (since "growing" is implemented as creating a new creature in place of the old one, so onCreaturesBorn() is also called)
- use creature's center (not the bbox corner) when growing
- added "S" receptor to visualize the difference between diplo and haplo generations
- signal.value is a MechPart (a reference) so it does not have to be updated after changing the object location
