Cargo Kconfig

The crate cargo-kconfig is both an extension on cargo as well as a set of macros allowing for an application to use Kconfig configuration files.

The cargo-kconfig crate contains the cargo-kconfig command (when installed through Cargo, this will also be usable as the command sequence "cargo kconfig"), which implements a basic Kconfig menu user interface.

When the cargo-kconfig crate is used by another crate it contains several Kconfig related macros, allowing for reading the Kconfig and associated .config files, along with macros enabling reading out the values.

Currently, the package is under heavy development, any suggestions to enhance the package are useful.
