27 | // ----------------------- | |
28 | // A generic set of functions (defined in the <decoder> namespace). | |
29 | // Used to decode formatted strings, eg. a list of integer ranges, | |
30 | // or a list of sub-strings separated by delimiters such as '(','{','[', ... . | |

32 | // (string 1) (string 2) [string3] {string4} [ (string5.1) (string5.2) ] | |
33 | // note : |_____________________| | |
34 | // | | |
35 | // this is just ONE substring. | |
