Index not displayed when a module does not contain classes and enums.

[KidyovrS]

This only happens with --mdEngine gitbook.

Source:

export interface IMyInterface {
}

export const MyVariable: string = "HelloWorld";

Actual:

# Variables

<a id="myvariable"></a>

## `<Const>` MyVariable

**● MyVariable**: *`string`* = "HelloWorld"

___

Expected:

# Index

### Interfaces

* [IMyInterface](../interfaces/_index_.imyinterface.md)

### Variables

* [MyVariable](_index_.md#myvariable)

---

# Variables

<a id="myvariable"></a>

## `<Const>` MyVariable

**● MyVariable**: *`string`* = "HelloWorld"

It's fine to hide index if the module only contains variables/functions, since they're directly documented in the module page. However I suppose interfaces should be treated the same as classes and enums.
