Original GitHub issue: https://github.com/atulmy/gql-query-builder/issues/88

If I try to create my custom Adapter as suggested in the docs , I cannot access Utils methods. For example this Adapter:

import Utils from 'gql-query-builder/build/Utils';

export default class MyQueryAdapter implements IQueryAdapter {
...
   this.variables = Utils.resolveVariables(options); ..
}

will throw an error like TypeError: Utils.resolveVariables is not a function

This happens because Utils is exported as an instantiable class with static functions, and while this works when importing it inside the gql-query-builder project itself, I cannot work in other projects that have a dependency to it.
