Export helper methods as named exports

[aronstrandberg]

Issue: #650

• Export all methods individually as named exports, instead of export all helpers as a default export in the form of an object
• Reorder the method definitions to counter eslint's no-use-before-define errors. This makes the diff look mighty weird, so it might be easier to look at the individual commits' diff

I'll be happy to make any changes you find necessary.

I don't know if you can squash the commits when merging – let me know otherwise and I can push a squashed version here.

@aronstrandberg thanks for this improvement. Actually, though, the I believe the only method that needs to be exported is getBaseProps. I will merge this work after that small change.

@boygirl thanks! I pushed two commits that should fix this
