We have four unknown parameters and four solvable equations. This function takes inputs and puts them into equations to estimate the value of these four unkown parameters, alpha, beta, omega, and N_eq, from inputs: adult infection (prevalence and intensity), child infection (prevalence and intensity), child and adult population sizes, infected snail prevalence

1 2	age_strat_get_pars(f = age_strat_fit_mod, start = c(0.01, 1000, 1e-06, 4), I, W_A, prev_A, H_A, W_C, prev_C, H_C, pars, tolerance = 1e-06)

`f`	function with equations to feed to 'multiroot' function. Defaults to 'age_strat_fit_mod'
`start`	input estimates of parameters beta, N_eq, alpha, and omega (IN THAT ORDER)
`I`	infected snail prevalence
`W_A`	estimated mean worm burden in adult population
`prev_A`	estimated prevalence in adult population
`H_A`	adult population size
`W_C`	estimated mean worm burden in child population
`prev_C`	estimated prevalence in child population
`H_C`	child population size
`pars`	parameter set of other key parameters
`tolerance`	minimum error to tolerate, else return error
