/** Random sampling of arrays or sequences.
    Limitations:  not 100% random. Tries to not start at 0 all the time, or get items at the exact end of list, but there are some biases.      
    Intended to get random blocks of contiguous items. Blocks are used for two reasons
       1. it is sometimes nice to only get ranges, then get the data later to avoid a huge URI or ID pull up front.
       2. each chunk is one pass through a loop, including random generation and adjustments. fewer/larger chunks goes faster than chunksize=1.
