Rework Guide (#486) * Move getting started to Guide * Clean up summary and getting started * Shorten intro by moving stuff to individual platform docs * Make intro even shorter, summarize features * Further cleanup; move development-related docs to separate section * Make `guide` a crate. Turn code samples into examples so that we can check if they compile * Rewrite "Describing the UI": * Focus on RSX syntax (interactivity covered in later chapters); make sure samples are tested; concise language * Move some "special attribute" samples to the `examples` directory * Simplify introduction to components * Simplify introduction to component props * Document Prop features; add code samples * Simplify component children docs * Interactivity: better introduction to events * Hooks: better introduction * Remove outdated doc * Introducs use_ref * Simplify User Input chapter * Document event handler props * Meme editor example * Meme editor walkthrough * Add dark mode example * Guide for context; dark mode example * Guide: custom hooks * Guide: conditional rendering * Guide: rendering lists * Guide: rendering lists + keys * Move remaining infor from Reference to guide * Delete reference book 2022-07-07 08:50:36 +00:00			`#![allow(non_snake_case)]`
