@Zeko369 CI is failing. Any updates on this?

I'm trying to get babel to use a custom config to transpile ES6+ to ES5 so we can use sequelize-cli, but kind off hit a wall. I'll push what I have and maybe someone can help

@Zeko369 is the roadblock on #120 and this issue that sequelize-cli-typescript doesn't work with the stack and so you're punting back to sequelize-cli? I can try to dig up some new volunteers from #11 if you think this is an issue TS devs or Sequelize devs can get around.

We seem to be blocked by an issue with Babel itself. There are possible workarounds.

require('babel-register')({
presets: 'es2015',
plugins: ['add-module-exports'],
});

Killing this PR, I'll do this in a new TypeORM pr
