DoubleData are basically doubles, that will do for now.
Basically, you could copy another two-paramter function (such as +-*/)
and rename it goto. It will then accept two doubles, which is fine. No
need to change that. You probably wanna make goto return a double
aswell, as you will get things like goto(goto(x,y), z) which won't
make sense otherwise.
