| /** |
| * Utility method to take a string and convert it to normal Java variable |

| * case when there is more than one character and both the first and |
| * second characters are upper case, we leave it alone. |
| * <p> |
| * Thus "FooBah" becomes "fooBah" and "X" becomes "x", but "URL" stays |
| * as "URL". |
| * |
| * @param name The string to be decapitalized. |
| * @return The decapitalized version of the string. |
