------------------------------------

Integrated in commons-collections #25 (See [https://builds.apache.org/job/commons-collections/25/])
    [COLLECTIONS-399] added more context information when throwing a NoSuchElementException.

> Since the BoundedFifoBuffer is implemented as an array, it should be simple to implement
random access to any element of the buffer.
> [This functionality was requested on the Commons user list]
> For example:
> // get nth entry; i.e. get(0) is the same as get()
> // NoSuchElementException if i >= numEntries
> // if i < 0, could either throw an Exception or treat as reverse index from end of
buffer
> E get(int i)
> This would also work for the sub-class CircularFifoBuffer.
