Why are types layout and point unexported?

[swd543]

I am not able to use these types in my code. I am not able to use half of the functions exposed by the library without having access to layout struct.

Similarly I would like to use hexgrid.hex directly, in structs, in function return types, etc. outside of the module, but since it's not exported I can't. I'm new to go, but I think the objective of not exporting these types is to prevent misuse from outside, i.e. you should call NewHex instead of constructing it yourself, but it does make it hard to use them practically from outside.
