Create a GUI helper application which can be given a tarball location (local or remote) and create a recipe skeleton to help people get started with recipe creation.

Steps we can perform:
* If a remote location set SRC_URI
* Generate checksums
* Create empty default fields (DESCRIPTION, SUMMARY, LICENSE, etc)
* Extract the archive to a temporary location and:
  - look for common license files (COPYING, COPYING.LIB, etc) and create a LIC_FILES_CHKSUM entry (otherwise an empty field)
  - look for common build system files and work out which classes to inherit. CMakeLists.txt -> inherit cmake, configure.[ac|.in] -> autotools, setup.py -> disutils(?), etc.

I propose we call the GUI Gran, because your gran shares the family recipes :-)
