in the library. extern tells the compiler that the functions
may be called in other files, such as main.cpp. void specifies 
that the function will not return a value, i.e. the program will 
execute the function and then move on the the next line of code. 
forward is the name of the function and float specifies that 
the function expects to be passed a variable of the format float. */
