feat(helpers): create helpers module

[jvandemo]

Currently helper functions like dashCase(), 'copy(), notMatched(), forEach(), etc are defined in individual modules.

Downside

• the helper functions cannot be unit tested directly
• the helper functions must be redefined in unit tests that require them (e.g. dashCase() is redefined here), making it hard to maintain them

Proposal

I would suggest bundling all helper functions in a helpers module and write unit tests for them.

The module could be called helpers so you can easily import required helpers in code and unit tests:

import {helpers} from '../src/helpers';

Plan

@btford — if you agree with the proposal, I am willing to invest the time to implement this and create a PR for it. Just wanted to check with you before I go ahead and implement it.

Feel free to let me know if you want to go ahead with this.

Sounds good to me. Thanks @jvandemo!

@btford — Thanks for the confirmation, I will make it happen.

I will also reference and close this issue when the PR has been created to keep things tidy.

PR #212 has been created. Proposal can be closed.
