Implement easy-breezy API for constructing bem-string

[Yeti-or]

original: bem/bem-sdk#165

Possible candidate:

import b from '@bem/naming';

b('button2')('text') // button2__text
b('popup') // popup
b('popup)({theme: normal}) // popup_theme_normal

zxqfox :

import { carrier } from '@bem/naming';
const carrier = require('@bem/naming/carrier');

carrier('button2')('text')...

skad0 :
carrier? seems pretty unexpected

b('button2').e('text').m({ theme: 'normal' })

As for me looks easier for reading and understanding.

zxqfox :

import { b_ } from '@bem/naming';
const b_ = require('@bem/naming/b_');

b_('button2')('text')...

I want!) World is ready to this magic)

I like skad0 implementation:

b('button2').e('text').m({ theme: 'normal' })

Also, would be great add mix helper:

const b1 = b('button2').e('text').m({ theme: 'normal', size: 'm' });
const b2 = b('sharik').e('palka').m({ dva: 'struna' });

b('dagestan').m({ moya: 'strana' }).mix(b1, b2);

Yeti-or :
awinogradov let's make it part of @bem/naming as
zxqfox suggested

awinogradov :
I've made temporary package easy-bem-naming for testing this kind API. We'll try to use it in the bem-react-core and then we can implement it here in bem-naming with stable API.
