def add_location_strategy(self,strategyName,functionDefinition):
self.do_command("<STR_LIT>", [strategyName,functionDefinition,])<EOL>
Defines a new function for Selenium to locate elements on the page.
For example,
if you define the strategy "foo", and someone runs click("foo=blah"), we'll
run your function, passing you the string "blah", and click on the element
that your function
returns, or throw an "Element not found" error if your function returns null.

We'll pass three arguments to your function:

*   locator: the string the user passed in
*   inWindow: the currently selected window
*   inDocument: the currently selected document


The function must return null if the element can't be found.

'strategyName' is the name of the strategy to define; this should use only   letters [a-zA-Z] with no spaces or other punctuation.
'functionDefinition' is a string defining the body of a function in JavaScript.   For example: ``return inDocument.getElementById(locator);``
