Bug 1553194 - Remove unrelated code comment from shared/css-logic.js r=pbro

Depends on D32016
The code comment is perhaps a leftover from a file duplication to extract shared methods to `shared/inspector/css-logic.js` from `server/actors/inspector/css-logic.js`.

The comment is confusing because there is no usage of any of the CssLogic terminology within the file.

- * About the objects defined in this file:
- * - CssLogic contains style information about a view context. It provides
- *   access to 2 sets of objects: Css[Sheet|Rule|Selector] provide access to
- *   information that does not change when the selected element changes while
- *   Css[Property|Selector]Info provide information that is dependent on the
- *   selected element.
- *   Its key methods are highlight(), getPropertyInfo() and forEachSheet(), etc
- *   It also contains a number of static methods for l10n, naming, etc
- *
- * - CssSheet provides a more useful API to a DOM CSSSheet for our purposes,
- *   including shortSource and href.
- * - CssRule a more useful API to a DOM CSSRule including access to the group
- *   of CssSelectors that the rule provides properties for
- * - CssSelector A single selector - i.e. not a selector group. In other words
- *   a CssSelector does not contain ','. This terminology is different from the
- *   standard DOM API, but more inline with the definition in the spec.
- *
- * - CssPropertyInfo contains style information for a single property for the
- *   highlighted element.
- * - CssSelectorInfo is a wrapper around CssSelector, which adds sorting with
- *   reference to the selected element.
