New Twins user interfaces - up to 3 twins !!

 I was experimenting several user interface ideas to support multiple twins.

After toying with 4 designs, I have decided on this interface.  Now there is support not just for a pair of twins but up to 3 of them!

In the old clunky application, I used a checkbox to denote twins.  In this refresh, I used some web UI tricks to allow users to toggle between twins.  See the screen capture below, a picture speaks a thousand words.

To avoid confusion, when you save the data, take note of the twin's number and input the number in the name!  This is a nifty mechanical trick.  

With this addition, I have surpassed the clone's implementation of the Si Hua Flying Stars web application. 

In addition, I took the opportunity to allow users to plot ancient charts, from 1885 to as recent as 2100.

I will post more screen captures of new features, stay tuned!
