+ * Development versions are also supported by adding an "a" character and more version info after

+ * before the "a" are different, the parts after the "a" are ignored. If the parts before the "a"
+ * are identical, the result of the comparison is the result of NUMERICALLY comparing the parts
+ * after the "a". If the part after the "a" is empty, it is treated as if it were "0". If one
+ * string has an "a" and the other does not (e.g. "3.0" and "3.0a1") the one without the "a"
+ * is newer.
+ *
+ * Examples (?? means undefined):
+ *   "3.0" = "3.0"
+ *   "3.0a2" = "3.0a2"
+ *   "3.0" > "2.5"
