Ranges

Ranges instead of atom masks.

For several commands some arguments are ranges (e.g. ’trajout onlyframes <range>’, ’nastruct resrange<range>’, ’rmsd perres range <range>’); THESE ARE NOT ATOM MASKS. They are simple number ranges using ’-’ to specify a range and ’,’ to separate different ranges.

For example

1-2,4-6,9

specifies 1 to 2, 4 to 6, and 9, i.e. ’1 2 4 5 6 9’.
