textBack explanation

doesn't return anything
validateName explanation

used to make sure the name the user enters is possibly an actual bus
stop name
validateNumString explanation

this function is used to check if the number entered is an actual
number, because the user needs to enter a number of minutes they want
to be reminded
validateBody explanation

this is what checks the full input of the user, and the text goes
through this before going further. If the text info is entered
incorrectly, it will text back that it is invalid
