"Issues an 'assertion failed!' error when its argument <vVariable> is nil. This function is equivalent to the following Lua function:"

function assert (v, m)
    if not v then
        m = m or ""
        error("assertion failed!  " .. m)
    end
end

<vVariable>: any declared variable.
<sMessage>: optional message to print. The message 'assertion failed!' is used by default.
