1. Modified buildIndex() so that only one connection is used for both indexing nodes and indexing paths. 2. Modified the indexing algo so that indexing of paths is done while nodes are being indexed. Results in a much faster indexing algo 3. Replaced access to NodeRecord.<variable> with NodeRecord.<getVariable>
