selectXPath and other functionalities of CasperJS

[ivikash]

Firstly, thank-you for spooky, but unfortunately I feel, its still not complete [or I am not able to find the suitable documentation], for functions like, selectXPath, assertExists etc.

If its already there, then can you please provide the necessary pointers and include it in docs.

I'm not familiar with selectXPath. assertExists, on the other hand, is not implemented by design, as it only makes sense to call inside a step function in Casper's JavaScript environment. Spooky only implements a subset of the Casper API: those methods that add steps and otherwise control the execution of suites.

Please see the Introduction in the wiki for an explanation of the different JavaScript environments in play. #7 tracks the need for API documentation.
