- * @description
- * The circular progress directive is used to make loading content in your app as delightful and
- * painless as possible by minimizing the amount of visual change a user sees before they can view
- * and interact with content.
- *
- * For operations where the percentage of the operation completed can be determined, use a
- * determinate indicator. They give users a quick sense of how long an operation will take.
- *
- * For operations where the user is asked to wait a moment while something finishes up, and it’s
- * not necessary to expose what's happening behind the scenes and how long it will take, use an
- * indeterminate indicator.
- *
- * @param {string} md-mode Select from one of two modes: **'determinate'** and **'indeterminate'**.
- *
- * Note: if the `md-mode` value is set as undefined or specified as not 1 of the two (2) valid modes, then **'indeterminate'**
- * will be auto-applied as the mode.
- *
- * Note: if not configured, the `md-mode="indeterminate"` will be auto injected as an attribute.
- * If `value=""` is also specified, however, then `md-mode="determinate"` would be auto-injected instead.
- * @param {number=} value In determinate mode, this number represents the percentage of the
- * circular progress. Default: 0
- * @param {number=} md-diameter This specifies the diameter of the circular progress. The value
- * should be a pixel-size value (eg '100'). If this attribute is
- * not present then a default value of '50px' is assumed.
- *
- * @param {boolean=} ng-disabled Determines whether to disable the progress element.
- *
- * @usage
