/**
* method: backtrace
*
* a method to obtain a debug backtrace of the current PHP function stack with options to
* slice a part of the array
*
* this function uses variable arguments, it will only slice the string if it first two
* parameters are integer numbers after that, all the arguments will be tested whether
* they are a string and if so, they will be used to filter each array stack element to
* return only the keys which match the strings, dropping all the unwanted keys from
* each array stack element
*
* parameters:
* $start - The starting offset to slice from the array stack
* $finish - the ending offset to slice from the array stack
* vargs - any number of string variables which will be used to filter each array index to reutrn only the keys requested
*
* notes:
* - The function is really really memory hungry, use Amslib_Debug::getStackTrace if you can
* - This is a really ancient function, it's hard to know what it's trying to do
