GurobiOpts-class

This class is used to store Gurobi input parameters.

Biodiversity is in crisis. The overarching aim of conservation
is to preserve biodiversity patterns and processes. To this end, protected
areas are established to buffer species and preserve biodiversity processes.
But resources are limited and so protected areas must be cost-effective. This
package contains tools to generate plans for protected areas (prioritizations),
using spatially explicit targets for biodiversity patterns and processes.
To obtain solutions in a feasible amount of time, this package uses the
commercial 'Gurobi' software package (obtained from <http://www.gurobi.com/>).
Additionally, the 'rgurobi' package can also be installed to provide extra
functionality (obtained from <http://github.com/jeffreyhanson/rgurobi>).
