v0.1.14

Added support for facets. New function:

• addFacetField

For example, faceting against genre:

client.addFacetField('custom_fields.genre')

could return

hits: [ ... ]
facets: {
  custom_fields.genre: [
    {
      value: "rock",
      count: 932
    },
    {
      value: "pop",
      count: 823
    },
    ...
