* Decided this tool was mature to the point it could be called 1.0.0.
0.0.6
------------------
* yaml.load() will accept a KiCad board file as legal YAML, so place additional checks to detect yaml files and prevent over-writing .kicad_pcb files with YAML.
0.0.5
------------------
* Rearranged hierarchy of board data to more closely reflect KiCad board setup dialog.
0.0.4
------------------
* Added ability to inject/eject plot settings (but not drill settings).

------------------
* Added ability to inject/eject layer enables and visibility.
0.0.2
