// 1: A "login successful" array that will have the following key/value pairs (note: the format is "key" -> "value"):
// - "Status" -> "true" // This is a boolean in the PHP file but gets converted to a string when the LoginResponse is constructed.
// - "Message" -> "Login successful" // This is a string
// - "Email" -> *Email* // This the Email of the user as a string
//
// 2: A "login unsuccessful" array that will have the following key/value pairs:
// - "Status" -> "false" // This is a boolean in the PHP file but gets converted to a string when the LoginResponse is constructed.
// - "Message" -> "Login unsuccessful: invalid email and password combination" // This is a string
//
// These associative arrays are then converted into a LoginResponse object via a call to JsonConvert.DeserializeObject().
// A LoginResponse object has get/set Status, Message, and Email functions -- these allow you to easily see if the attempted login was successful.
