ZF-10216: Zend_Filter_Word_CamelCaseToUnderscore is not the opposite of Zend_Filter_Word_UnderscoreToCamelCase

Description

A user could assume that Zend_Filter_Word_CamelCaseToUnderscore is the opposite of Zend_Filter_Word_UnderscoreToCamelCase.

The result instead could be different due to letter casing, adding to the documentation an example like the following could be helpful.

 
     first_name
 
          => Zend_Filter_Word_UnderscoreToCamelCase 

               =>FirstName

                     => Zend_Filter_Word_CamelCaseToUnderscore 

                            => First_Name
