use Genome * to make polymorphism easier. Set genome_id only at beginning
genomemgr stub
allow selection of pop type from cmd line
can't rely on derived virtual function from base constructor
pass rng_t copy to make reasoning about state easier
seed populations with full generation of genomes
pass genome_manager to species pop
pass genome_manager to deme pop
use GenomeManager in populations
use unique_ptr<Genome>
facilitate polymorphic Genome
Genome base class
Create src directory structure to deal with large set of files.
further file reorganization
initial space genome implementation (runtime errors)
reduce node type/place to just node type
space genome running without errors
support pop_type and genome_type
enable mutation on mate
permit sending of only global elites
