/**
* <p>
* Provides an {@link java.lang.reflect.InvocationHandler} which
* implements a series of accessor methods (those beginning with
* {@code "get"} or {@code "is"}) using the content of a
* {@link CompositeData} object. An instance of {@link CompositeData}
* consists of a series of key-value mappings. This handler assumes
* these keys to be the names of attributes, and thus provides
* accessor methods by returning the associated value.
* </p>
* <p>
* As an example, consider the following interface:
* </p>
* <pre>
* public interface Person
* {
* public String getName();
* public Date getBirthday();
* }
* </pre>
* <p>
* This specifies two accessor methods for retrieving the attributes,
* {@code name} and {@code birthday}. An implementation of this interface
* can be provided by creating an instance of this class, using a
* {@link CompositeData} object with appropriate key-value mappings
* (e.g. "name" => "Fred", "birthday" => 30/06/1974), and then passing
* that to {@link java.lang.reflect.Proxy#newProxyInstance} along with
* the interface itself. The invocation handler implements the methods
* by calling {@link CompositeData#get(String)} with the appropriate key.
* </p>
* <p>
* The attribute name is derived by taking the remainder of the method
* name following {@code "get"}. If the first letter of this substring
* is uppercase, then two attempts are made to retrieve the attribute
* from the {@link CompositeData} instance: one using the original substring,
* and one with the first letter changed to its lower-case equivalent.
* If the first letter is lowercase, only the exact substring is used.
* </p>
* <p>
* An {@link Object#equals(Object)} implementation is provided. This returns
* true if the argument is a proxy with a {@link CompositeDataInvocationHandler}
* using an equivalent {@link CompositeData} instance. {@link Object#hashCode()}
* is also defined so as to match this implementation and give equivalent instances
* the same hashcode.
* </p>
