Returns the starting position of the first occurrence of the specified target list within the specified source list, or -1 if there is no such occurrence. More formally, returns the lowest index i such that source.subList(i, i+target.size()).equals(target), or -1 if there is no such index. (Returns -1 if target.size() > source.size())

This implementation uses the "brute force" technique of scanning over the source list, looking for a match with the target at each location in turn.

Parameters:

source		the list in which to search for the first occurrence of target.
target		the list to search for as a subList of source.

Returns:  the starting position of the first occurrence of the specified target list within the specified source list, or -1 if there is no such occurrence.
