Make the second parameter of PrevVal optional

The PrevVal function currently requires two parameters: an attribute and a timestamp. However, I find that 90% of the time that I use this function I am looking for the previous value with respect to the current time ('*'). The error which analytics throws does not make this error apparent, and it seems like making the second parameter optional (with the default being '*' would provide a better user experience).

    This function has been around for a long time and changing its behavior, even though it would be optional, may be too confusing for users who have to manage legacy calculations with new calculations. The potential tech support cost vs. benefit ratio does not support our implementation of this request.
