[R] Splitting up the micEcon package?

Dear Arne and Ott-Simm

It always seemed weird to me mixing demand and firm models with SSel.
models on a single package.

Separating them would seem the logical thing to do.

On the other hand, one more R package :/ , I´m not too big of a fan of
increasing this list ad infinitum.

My take on this is that it would be worth it to split it if you think
you´ll keep expanding the SSel. models under the new package.
Otherwise keep it the way it is.

I still dream of contributing a package that offers a group of SSel.
models under a wide variety of settings, but still haven´t found the
time to do so, nor it seems i´ll have it in the near future. On the
other hand, judging by the low number of replies it seems to me that
the audiece for SSel. in R is still quite limited.

My two cents,
