Use this instead of String.compareTo() for a non-lexicographical comparison that works for version strings. e.g. "1.10".compareTo("1.6").

Parameters:

str1 - a string of ordinal numbers separated by decimal points.

str2 - a string of ordinal numbers separated by decimal points.

Returns:

The result is a negative integer if str1 is _numerically_ less than str2. The result is a positive integer if str1 is _numerically_ greater than str2. The result is zero if the strings are _numerically_ equal. N.B. It does not work if "1.10" is supposed to be equal to "1.10.0".
