valid_ct() fails for sequences that start with .

Thanks for the great package!

If you change your example dot bracket notation to start with a dot (and change the final bracket as well), the code fails.

This is because pos '1' - bound '0' = <2

I assume this is a mistake.

ct=makeCt(".(((...(((((((....)))))))...((((...))))...))).",
