deployment schemes: [pre-defined] all-in-one

[mauriceling]

1. Deployment scheme is to allocate organisms to a particular eco-cell before the simulation starts (before generation 1).
2. Deployment schemes will be given as part of simulation parameters.
3. We should have an All-in-one deployment scheme where the entire population gets parachuted into just one eco-cell.
4. All-in-one deployment scheme to have deployment_code=1.

Implemented deployment scheme: all-in-one. Works in the latest pull request (Implemented deployment schemes 1-4).

1. Entire population is deployed inside one cell.
2. Ignores the 'eco_cell_capacity' key in the parameters.
