a fairly intense bout of demolition;  the main point is to separate the basekb-core project from the rest of the system.  Rather than moving basekb-core dependencies elsewhere it came down to rather indiscriminant slashing against anything that depeneded on the old FreebaseQuad (Infovore 1.0 era) and some functions involving NQuads that could be useful later may have been lost,  also the system for keeping track of the relationship between different data sets at different times (constellations) has been smashed and now most of the 1.1 era applications are gone in 2.0 .  some of this stuff that's been deleted,  such as PSE itself,  are about to be revisited,  but that is why we have version control
