Have Associations in initModel

[vivekkairi]

Currently init-models.ts has all the associations of all the models, that makes it ugly and difficult to read. Shifting assocations to models file simplies things and makes it more readable

static initModel(sequelize: Sequelize.Sequelize): typeof user { let model = user.init({ }) model.hasOne(otherModel) return model }

I hope so, too Let's implement it quickly.
