Validates a JSON parsed as a map json given a JSON schema schema.

Returns {:ok} if the schema has validated correctly. Otherwise, returns:

  {:error,
    [
      %{
        error: "String with Error Description",
        property: "String with property involved in error"
      }
    ]
  }

...>   "$schema" => "http://json-schema.org/draft-04/schema#",
...>   "type" => "object",
...>   "properties" => %{
...>     "surname" => %{"type" => "string"}
...>   },
...>   "required" => ["surname"],
...>   "additionalProperties" => false
...> }
iex> alias JsonSchemaValidator.JsonSchema
iex> JsonSchema.validate(%{"surname" => "Smith"}, schema)
{:ok}
