This is the change log for the WebMathXpert project.

8.17.23   
1.  This file created.   Recently I registered mathxpert.org, where I'll experiment with this project.
2.  Currently there are two program files:  server.c  and index.php,  both written by ChatGPT,  to demonstrate
    the client-server architecture I have in mind.
3.  Created Spec.tex,  in which I will write the specification document. 

9.2.23

4.  server.c and index.php are working now as follows:  you enter "polygon n",  that goes 
to server.c, which stores n in your document, identified by sessionId, in a hash table,
svgGenerator.c  generates SVG code to draw the polygon, which is sent back to index.php 
via socket and then to the browser to draw;  the polygon_history message is then sent
and received and processed, and the result echoed to the browser.  Javascript file mouse.html
exists but does not send the selection rectangle back to PHP yet.  

Next:  have the C code send graphics line by line,  with svg headers statically index.php
