Title: Fix for scene locate method

I discovered that scene#locate was not behaving correctly. I took the liberty of writing some unit tests for locate and fixing the bug. The regrid method calculated the locateObj gridX1,Y1 and gridX2,Y2 to NaN and then the gridTest was failing to locate the item in the grid.
