--[[
    CoreAPI is designed to provide some of the regularly needed
    features of general types of programs in one place.

    It is a mish-mash of functions where I wasn't sure where to place
    elsewhere.

--==Startup Functions==--

--Test This
function setStartup(...)
  --Takes any number of arguments and creates
  --a startup script to execute the program (argument 1)
  --with any following parameters (arguments afterwards)

  --Making sure I don't break a previous startup

--==Update Functions==--

end

function writeStartup(...)
    --Generates a startup program which will automatically update
    --programNames with URLs every reboot.

    --Work on this--
