/*
* webu_html.c
*
* Create the html for the webcontrol page
*
* This software is distributed under the GNU Public License Version 2
* See also the file 'COPYING'.
*
* Functional naming scheme
* webu_html* - Functions that create the display webcontrol page.
* webu_html_main - Entry point from webu_ans_ctrl(in webu.c)
* webu_html_page - Create the web page
* webu_html_head - Header section of the page
* webu_html_style* - The style section of the web page
* webu_html_body - Calls all the functions to create the body
* webu_html_navbar* - The navbar section of the web page
* webu_html_config* - config parms of page
* webu_html_track* - Tracking functions
* webu_html_script* - The javascripts of the web page
*
* To debug, run code, open page, view source and make copy of html
* into a local file to revise changes then determine applicable section(s)
* in this code to modify to match modified version.
* Known HTML Issues:
* Single and double quotes are not consistently used.
* HTML ids do not follow any naming convention.
* After clicking restart, do something...Try to connect again?
*
* Additional functionality considerations:
* Notification to user of items that require restart when changed.
* Notification to user that item successfully implemented (config change/tracking)
* List motion parms somewhere so they can be found by xgettext
*
