-/* 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
