Title: Fix Grammar

Fix minor grammar error in comment. No source code was changed.

Before:
```
/**
* Implements a circle, or spherical, geometry for an Body with
* radius.
*
* @class Circle
* @extends Body
* @constructor
*/
```

After:
```
/**
* Implements a circle, or spherical, geometry for a Body with
* radius.
*
* @class Circle
* @extends Body
* @constructor
*/
```
