evaluate_first: evaluate_first
In jhoffjann/nmmso.R: R Implementation of the NMMSO algorithm

Calculates the first evaluation of the swarms.

1	evaluate_first(swarm, problem_function, nmmso_state, swarm_size, mn, mx)

`swarm`	Swarm object
`problem_function`	String containing name of function to be optimised.
`nmmso_state`	Structure holding state of swarm.
`swarm_size`	Maximum number of elements (particles) per swarm.
`mn`	Minimum design parameter values (a vector with param_num elements).
`mx`	Maximum design parameter values (a vector with param_num elements).
`problem_function_params`	Meta-parameters needed by problem function.
