Checks of two states to be less. If name < e.name then it returns true. if name > e.name then it returns false. If name is equal e.name then it checks the values of the headers stack indexes. For both map of header stacks' indexes it creates map of pairs of values for each header stack index. If some indexes are missing then it cosiders them as -1. Next, it continues checking each pair in a intermidiate map with the same approach as for name and e.name.
