Because node_modules exists within the EUI project dir, yarn linking EUI into another project can create conflicts between dependency versions, most notably with React. Another recurring "issue" when testing EUI linked into another project is forgetting to buildchanges to EUI.

I'd like to add a new script in EUI that mimics a linking behaviour by building & copying the es and lib directories to a specified project, then watch for changes to EUI sources and update the es and lib builds on additional changes.

Something like yarn build-into ~/projects/kibana
