Computed field types

[eschnett]

Your package uses bitstype(T) to obtain the "real" type for some types.

In case you are not aware, I want to point to the package Computed FieldTypes which does a similar thing, but uses a different function name (fulltype) for a very similar functionality.

You might want to point to this package in your documentation if you think it's worthwhile, or you could work with @vtjnash to use the same API in both packages.

In the context of CBinding's usage at least, bitstype(T) is semantically much more precise, and isbitstype(bitstype(T)) is both always true and very intuitive. Also, the use of bitstype(T) is just a temporary artifact of having to work around JuliaLang/julia#269.
