Create object/pathOr

[joelnet]

Need to create a function to deep select an object or provide a default value.

Expected

const customer1 = {
  address: {
    state: 'CA'
  }
}

const customer2 = { }

pathOr ('--') ([ 'address', 'state' ]) (customer1) //=> 'CA'
pathOr ('--') ([ 'address', 'state' ]) (customer2) //=> '--'

Acceptance Criteria

• object/pathOr.js is created
• unit tests are created.
