/**
* Example: Status and Reset
* Description:
* This example is very similar to the "mininal" example.
* But here we provide a status indicator LED, to get feedback
* of the thing state.
* Further more we set up a push button. If push button is detected
* to be pressed at boot time, the thing will use the initial
* password for accepting connections in Access Point mode. This
* is usefull e.g. when custom password was lost.
* (See previous examples for more details!)
*
* Hardware setup for this example:
* - An LED is attached to LED_BUILTIN pin with setup On=LOW.
* This is hopefully already attached by default.
* - A push button is attached to pin D2, the other leg of the
* button should be attached to GND.
