Exporting logit_model_nonprobsvy and others

[BERENZ]

Shall we export logit_model_nonprobsvy, probit_model_nonprobsvy, cloglog_model_nonprobsvy and pop.size functions?

[Kertoo]

pop.size should be exported (and renamed to pop_size) but the rest are meant to be internal functions

[BERENZ]

OK. Regarding the naming shall we apply this to controlInf (control_inf), controlOut (control_out), controlSel (control_sel) and genSimData (gen_sim_data)? I imagine that changing this may cause problems but maybe this is the right time (before CRAN submission)? This should be reported as a breaking change in the NEWS file. What do you think @LukaszChrostowski ?

[LukaszChrostowski]

Hmm, yes, we should be consistent here

[LukaszChrostowski]

Regarding logit_model_nonprobsvy, the reason of exporting this is usage that 'internal' function in Cpp implementation of variables selection algorithms, without exporting - the Cpp file can not see it, my solution looks naively a bit, so let me find something better, maybe you @Kertoo have any ideas?

[BERENZ]

@bschneidr maybe you could provide some suggestions regarding this issue? Currently, the function logit_model_nonprobsvy is exported so Rcpp can be used for the variable selection.
