An ES6 string tag that makes indentation right, adds some key features to [dedent](https://github.com/dmnd/dedent).

## Feature

### Pretty object

```ts
import dedent from "dedent";
import endent from "endent";

var someobj = {
  contact: {
    jack: 123456,
    tom: 654321,
  },
  color: "blue",
};

var somejson = '["bear", "fish", "dog", "cat"]';

var awfulTmpl = dedent`
  function store (state, emitter) {
    state["someobj"] = ${JSON.stringify(someobj, null, 2)}
    state["somejson"] = ${JSON.stringify(JSON.parse(somejson), null, 2)}
  }
`;
// use endent.pretty(value) when value is object or array.
var prettyTmpl = endent`
  function store (state, emitter) {
    state["someobj"] = ${endent.pretty(someobj)}
    state["somejson"] = ${somejson}
  }
`;

console.log(awfulTmpl + "\n\n" + prettyTmpl);
```

```ts
// awfulTmpl
function store(state, emitter) {
  state["someobj"] = {
contact: {
  jack: 123456,
  tom: 654321,
},
color: "blue",
}
  state["somejson"] = [
"bear", 
"fish", 
"dog",
"cat"
]
}

// prettyTmpl
function store(state, emitter) {
  state["someobj"] = {
    contact: {
      jack: 123456,
      tom: 654321,
    },
    color: "blue",
  }
  state["somejson"] = [
    "bear", 
    "fish", 
    "dog", 
    "cat"
  ]
}
```

### Endows suitable indentation for multiline interpolation

```ts
var dependencies = ["jquery", "underscore", "bootstrap"];
var dependencyTmpl = ``;
dependencies.forEach((d, i) => {
  dependencyTmpl += `var ${d} = require("${d}")\n`;
});

var awfulTmpl = dedent`
  ;(function () {
    ${dependencyTmpl}
  })()
`;

var prettyTmpl = endent`
  ;(function () {
    ${dependencyTmpl}
  })()
`;

console.log(awfulTmpl + "\n\n" + prettyTmpl);
```

```js
// awfulTmpl
(function () {
  var jquery = require("jquery");
var underscore = require("underscore");
var bootstrap = require("bootstrap");
})();

// prettyTmpl
(function () {
  var jquery = require("jquery");
  var underscore = require("underscore");
  var bootstrap = require("bootstrap");
})();
```
