make optimizer backend switchable

[russelljjarvis]

Through Julia batch scripts two packages for bio-inspired algorithms have been found to be effective, in single cell and network optimizations. Those are 1. Evolutionary.jl, 2. Metahieristics.jl. Both of these two packages have different APIs and different expected inputs and outputs. It is not extensively known if one performs more efficient optimization than the other.

Both of these bio-inspired algorithm packages should be wrapped with a higher-level API, such that either backend can be easily switched between, in order to explore which is the most effective optimization package (or perhaps neither is significantly better than the other).

make optimizer backend switchable between Evolutionary.jl and Metahieristics.jl

Example call Evolutionary API:
