// This file contains the webserver code for the ESP Single Channel Gateway.
// Note:
// The ESP Webserver works with Strings to display html content.
// Care must be taken that not all data is output to the webserver in one string
// as this will use a LOT of memory and possibly kill the heap (cause system
// crash or other unreliable behaviour.
// Instead, output of the various tables on the webpage should be displayed in
// chucks so that strings are limited in size.
// Be aware that using no strings but only sendContent() calls has its own
// disadvantage that these calls take a lot of time and cause the page to be
// displayed like an old typewriter.
// So, the trick is to make chucks that are sent to the website by using
// a response String but not make those Strings too big.
//
// Also, selecting too many options for Statistics, display, Hopping channels
// etc makes the gateway more sluggish and may impact the availabile memory and
// thus its performance and reliability. It's up to the uer to select wisely!
