Mapping enum types to enum values

[rickyp-uber]

When translating thrift enums like so:

enum EntityErrorType {
    UNKNOWN = 0,
    NOT_EXIST,
    EXISTED,
}

Thrift2Flow generates two objects

export type EntityErrorTypeTypeValues = 0 | 1 | 2;
export type EntityErrorTypeType = 'UNKNOWN' | 'NOT_EXIST' | 'EXISTED';

Is there a way in flow to map these back to one another through flow or through this tool? Would it make more sense for this tool to generate out a single object like so?

export type EntityErrorTypeType = {
   'UNKNOWN': 0,
   'NOT_EXIST': 1,
   'EXISTED': 2
};

#17 should resolve this when merged by creating an new type called EntityErrorTypeTypeMap

You probably want to export a const and not a type.

ie

export const EntityErrorEnum = {
  UNKNOWN: 0,
  NOT_EXIST: 1,
  EXISTED: 2
};

// usage
import {EntityErrorEnum, type EntityErrorType} from 'path/to/thrift/def.thrift';

function (error:  EntityErrorType) {
  if (error === EntityErrorEnum.UNKNOWN) {
    // do something
  } else {
    // do something else
  }
}

Yea I ran into that when attempting to use it. Should be fixed in the latest version of the pull request #17
