-/**
- * Implements Mozilla Toolkit's nsIVersionComparator
- *
- * Version strings are dot-separated sequences of version-parts.
- *
- * A version-part consists of up to four parts, all of which are optional:
- * <number-a><string-b><number-c><string-d (everything else)>
- * A version-part may also consist of a single asterisk "*" which indicates
- * "infinity".
- *
- * Numbers are base-10, and are zero if left out.
- * Strings are compared bytewise.
- *
- * For additional backwards compatibility, if "string-b" is "+" then
- * "number-a" is incremented by 1 and "string-b" becomes "pre".
- *
- * 1.0pre1
- * < 1.0pre2  
- *   < 1.0 == 1.0.0 == 1.0.0.0
- *     < 1.1pre == 1.1pre0 == 1.0+
- *       < 1.1pre1a
- *         < 1.1pre1
- *           < 1.1pre10a
- *             < 1.1pre10
- *
- * Although not required by this interface, it is recommended that
- * numbers remain within the limits of a signed char, i.e. -127 to 128.
