automate the cert renewal process

Script assumes user has ntru.
Script does not assume user has keygen and certgen enabled. 
If they do not, no certs will be updated as the purpose of this script is to update ALL certs without exception. Logic follows:

___if (ntru defined) {
______update certs, config with ntru, enable certgen/keygen, make check, generate ntru certs/key
______copy/paste ntru certs/key into certs directory
___}
___else (ntru undefined) {
______run config with ntru, enable certgen/keygen, run make check.

______if (ntru was found and is now defined) {
_________copy/paste ntru certs/key into certs directory
_________update the other certs too
______}
______else (ntru still undefined) {
_________do nothing, alert user of lack of ntru, tell them which one to clone from github.
_________after which, run this script again to update ALL certs at one time.
______} end if
___} end if
