-/* General Note About ESP8266
-
- ESP8266 is controlled by using AT commands sent via Serial. Most of the API
- is implemented with AT commands. You can find the list of all AT commands at
- https://nurdspace.nl/ESP8266

- Inputs:
- 1. MODSERIAL* input - Pass in a reference to a MODSERIAL object. This MODSERIAL object should be connected to the
- ESP8266 module's pins 3 and 4. MODSERIAL is used instead of regular serial because it has buffering capability.
- 2. char* inputSSID - Pass in a reference to a character array consisting of the SSID of the wireless network you
- want to connect to. Currently the library assumes that you are passing in the correct SSID and won't do any error
- checking.
- 3. char* inputPassword - Pass in a reference to a character array consisting of the password/shared key of the wireless network you
- want to connect to. Currently the library assumes that you are passing in the correct password and won't do any error
- checking.

- TODO:
- 1. Error checking of SSIDs by calling listOfAccessPoints() method and checking if the inputSSID is in the output of
- listOfAccessPoints() method.
- 2. Error checking of passwords by trying to actually connect the access point
