Did you stupdy the RealMagic search routine? I had a quick look, but it
seems like just another zonal algorithm.

It _is_ PMV with a few extra predicitions, slightly modifies treshholds, 
no "large" diamond (because Alexis says it's not needed anymore). 

Also, when new ME is integrated, we might migrate that to make it 
even closer to EPZS anyway. I wanted to migrate anyway, but EPZS+BFrames
is a compination that has to be studied a little more. 
However, it won't be necessary to have two very similar MEs. A faster one
like "ZeroSearch" (test only (0,0)) or a slower one like
"FullSearch" might however be interesting to switch on.
