/**
* Associates the given key with the given value. If the given key has multiple levels (consists
* of multiple strings separated by '.'), the property value is stored such that it can be
* retrieved either directly, by calling get() and passing the entire key; or indirectly, by
* decomposing the key into its separate levels and calling get() successively on the result of
* the previous level's get. <br>
* For example, given <br>
* <code>
* PropertyTree tree = new PropertyTree();
* tree.set( "a.b.c", "something" );
* </code> the following statements are equivalent ways to retrieve the value: <br>
* <code>
* Object one = tree.get( "a.b.c" );
* </code> <code>
* Object two = tree.get( "a" ).get( "b" ).get( "c" );
* </code><br>
* Note: since I can't have the get method return both a PropertyTree and a String, getting an
* actual String requires calling toString on the PropertyTree returned by get.
