Utility: set competition coefficients

set_competition(n_species, int_type, alpha, alpha_scale, inv_sign)

`n_species`	Number of species in a simulated community.
`int_type`	Generation method for an interaction matrix. Either `"constant"` or `"random"`. If `"random"`, competition coefficients are randomly generated with an exponential distribution Exp(1/alpha). If `"constant"`, competition coefficients are constant or supplied as a full matrix.
`alpha`	Competition coefficient. If `int_type = "constant"`, constant or a full matrix . If `int_type = "random"`, alpha represents the expected value of an exponential distribution. Provide a full matrix if `int_type = "manual"`.
`alpha_scale`	Logical. If `TRUE`, competition coefficients are scaled by carrying capacity.
`inv_sign`	Logical. Indicate whether the sign of competition coefficients is multiplied by minus one. If `TRUE`, values in `alpha` will become `-alpha` internally. For example, with a Ricker model, the equation will be `x * exp(r - alpha * x)` (`x * exp(r + alpha * x)` if `inv_sign = FALSE`)
