FindBy

```
@Retention(RUNTIME)
@Target({FIELD,TYPE})
public @interface FindBy
```
Used to mark a field on a Page Object to indicate an alternative mechanism for locating the element or a list of elements. Used in conjunction with PageFactory this allows users to quickly and easily create PageObjects.
It can be used on a types as well, but will not be processed by default.
You can either use this annotation by specifying both "how" and "using" or by specifying one of the location strategies (eg: "id") with an appropriate value to use. Both options will delegate down to the matching By methods in By class.
For example, these two annotations point to the same element:
```
 @FindBy(id = "foobar") WebElement foobar;
 @FindBy(how = How.ID, using = "foobar") WebElement foobar;
 
```
and these two annotations point to the same list of elements:
```
 @FindBy(tagName = "a") List<WebElement> links;
 @FindBy(how = How.TAG_NAME, using = "a") List<WebElement> links;
 
```
