Beta version of Data base and Analysis

I redesigned the network statistics data base. It has asynchronous and synchronous methods and the addRecord interface has changed along with the data structure of the data base.
networkAnalysis.js now pulls in data from the data base and analyses it. This needs improvement but it works for now.
There are new global objects: netStats for the network analysis object and netStatsDB for the data base object.
There is a test file under tests/netAnalysisTest.html that shows sample code for using the API.
