Methods summary
`public`	# `Auth_OpenID_Mapping( $classic_array = null )` Initialize a mapping. If $classic_array is specified, its keys and values are used to populate the mapping. Initialize a mapping. If $classic_array is specified, its keys and values are used to populate the mapping.
`public static`	# `isA( $thing )` Returns true if $thing is an Auth_OpenID_Mapping object; false if not. Returns true if $thing is an Auth_OpenID_Mapping object; false if not.
`public`	# `keys( )` Returns an array of the keys in the mapping. Returns an array of the keys in the mapping.
`public`	# `values( )` Returns an array of values in the mapping. Returns an array of values in the mapping.
`public`	# `items( )` Returns an array of (key, value) pairs in the mapping. Returns an array of (key, value) pairs in the mapping.
`public`	# `len( )` Returns the "length" of the mapping, or the number of keys. Returns the "length" of the mapping, or the number of keys.
`public`	# `set( $key, $value )` Sets a key-value pair in the mapping. If the key already exists, its value is replaced with the new value. Sets a key-value pair in the mapping. If the key already exists, its value is replaced with the new value.
`public`	# `get( $key, $default = null )` Gets a specified value from the mapping, associated with the specified key. If the key does not exist in the mapping, $default is returned instead. Gets a specified value from the mapping, associated with the specified key. If the key does not exist in the mapping, $default is returned instead.
`public`	# `_reflow( )`
`public`	# `del( $key )` Deletes a key-value pair from the mapping with the specified key. Deletes a key-value pair from the mapping with the specified key.
`public`	# `contains( $value )` Returns true if the specified value has a key in the mapping; false if not. Returns true if the specified value has a key in the mapping; false if not.
