Internal class used to read and write values for Map backed objects that use key/value pairs. The specified "key" is
used when invoking getter/setter. It is assumed that Map setter method has two parameters (for "key" and "value"),
but getter method one parameter (for "key").
<p>
Overloaded methods are supported. Map class can have two set methods with different signatures, but class will
choose the one with appropriate number of parameters.
<p>
Only intended for internal use.
