Wouter Buckens 000dd4c1c2 Add docs & example for SystemParam (#1435) ... It took me a little while to figure out how to use the `SystemParam` derive macro to easily create my own params. So I figured I'd add some docs and an example with what I learned. - Fixed a bug in the `SystemParam` derive macro where it didn't detect the correct crate name when used in an example (no longer relevant, replaced by #1426 - see further) - Added some doc comments and a short example code block in the docs for the `SystemParam` trait - Added a more complete example with explanatory comments in examples		2021-03-03 03:11:11 +00:00
