TSLint rule to prevent class inheritance.

## Install

```bash

npm install --save-dev tslint-no-subclass

```

## Usage

Add the following to `tslint.json`:

```json

{

    "extends": [

        "tslint-no-subclass"

    ],

    "rules": {

        "no-subclass": true

    }

}

```

### Allow inheritance for specific classes

```json

{

    "extends": [

        "tslint-no-subclass"

    ],

    "rules": {

        "no-subclass": [true, "Foo", "Bar"]

    }

}

```

## Example

Config:

```json

{

    "extends": [

        "tslint-no-subclass"

    ],

    "rules": {

        "no-subclass": [true, "Allow"]

    }

}

```

Source code:

```typescript

class Allow {}

class Valid extends Allow {} // Valid because "Allow" was added to rule exceptions

class Disallow {}

class Invalid extends Disallow {} // Error: Subclass not allowed

```
