Dev Time Warnings

[huntabyte]

Something like this that is tree-shakable could alleviate some issues people have especially with things like incorrect use of child snippet where buttons wrap buttons, etc.

let history: Set<string>;
if (process.env.NODE_ENV !== 'production') {
  history = new Set<string>();
}

export function warn(...messages: string[]) {
  if (process.env.NODE_ENV !== 'production') {
    const key = messages.join(' ');
    if (!history.has(key)) {
      history.add(key);
      console.warn(`Bits UI: ${key}`);
    }
  }
}
