LISTS: Extract every other element

[Randall Hopper]

Christian Tismer:
 |Your results are most interesting. Mike did the Numeric tests

I figured it wouldn't be fair not to have the output of all algorithms be
the same type of list.

 |I also assume that you do one test after the other, many times?
 |If not, I loose! :-))

I thought about that.  But the difference isn't that much.  One would think
the algorithms at the bottom might pay a price due to increased memory
fragmentation and garbage collection overhead, but commenting out all but
one (yours or the mxTools fragment for example) reveals a difference in the
0.01-0.03 second range.  Background noise.
