I have been working with the bean patterns that Netbeans provides and
I have found that the code generated for index property that is not
really useful since the memory allocation and other issues are not
taken care of. 

It will help if the implementation of the indexed property allows me
to specify if I want to use a Vector/ArrayList or a Hashtable/HashMap
for storing the properties.

I can help in making this enhancement if you can give me some pointers
as to where the enhancement needs to be made in the netbeans tree since
I assume its more like the template that has been used for the existing
property types.
