A workout creator for mrc or erg file formats

# workout-creator
A javascript library where you can create workouts in the mrc or erg file formats

# Usage

## Creating a workout
This will create a empty workout
```js
import { Workout } from "@stefanfortuin/workout-creator"

let workout = new Workout();
```

## Creating an interval
An interval needs to have duration and a percentage of the workload you are going to do

An interval's start and end time will be converted to "minutes.seconds" where the seconds parameter is a total of 100 instead of 60

```js
  import { Interval } from "@stefanfortuin/workout-creator"
  let duration = 120; // duration in seconds
  let percentage = 70;
  let interval = new Interval(duration, percentage)
```


## Adding intervals to a Workout

### One interval
```js
import { Interval } from "@stefanfortuin/workout-creator"

let interval = new Interval(120, 80), // 2 min duration on 80%

workout.addInterval(interval);
```

### Multiple intervals
```js
import { Interval } from "@stefanfortuin/workout-creator"

let intervals = [
    new Interval(120, 80), // 2 min duration on 80%
    new Interval(10, 120), // 10 sec duration on 120%
    new Interval(120, 80), // 2 min duration on 80%
]

workout.addIntervals(intervals);
```


## Saving the file
Right now it only saves the whole workout to a string.
You can put the string in a blob to download the file from the web or save it in to a file.
For now only 'mrc' and 'erg' file formats are supported

```js
workout.save('mrc');
workout.save('erg');
```
