* @ngdoc directive

* @module material.components.progressLinear
* @restrict E
*
* @description
* The linear 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. Each operation should only be represented by one activity indicator—for example, one refresh operation should not display both a refresh bar and an activity circle.
*
* 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 four modes: determinate, indeterminate, buffer or query.
* @param {number=} value In determinate and buffer modes, this number represents the percentage of the primary progress bar. Default: 0
* @param {number=} md-buffer-value In the buffer mode, this number represents the precentage of the secondary progress bar. Default: 0
*
* @usage
* <hljs lang="html">
* <md-progress-linear md-mode="determinate" value="..."></md-progress-linear>

* <md-progress-linear md-mode="determinate" ng-value="..."></md-progress-linear>
