### Typical use: Determinate

MDCActivityIndicator instances can be shown as determinate by modifying the `indicatorMode`
property and setting a percentage progress with `progress`. `progress` must be set to a floating
point number between 0 and 1. Values beyond this range will be capped within the range.

Note: Activity indicators are hidden unless they are animating, even if the indicator is determinate
progress.

#### Swift
```swift
let activityIndicator = MDCActivityIndicator()
activityIndicator.sizeToFit()
activityIndicator.indicatorMode = .determinate
activityIndicator.progress = 0.5
view.addSubview(activityIndicator)

// To make the activity indicator appear:
activityIndicator.startAnimating()

// To make the activity indicator disappear:
activityIndicator.stopAnimating()
```

#### Objective-C

```objc
MDCActivityIndicator *activityIndicator = [[MDCActivityIndicator alloc] init];
[activityIndicator sizeToFit];
activityIndicator.indicatorMode = MDCActivityIndicatorModeDeterminate;
activityIndicator.progress = 0.5;
[view addSubview:activityIndicator];

// To make the activity indicator appear:
[activityIndicator startAnimating];

// To make the activity indicator disappear:
[activityIndicator stopAnimating];
```
