initial commit for maximizing reflectance using the compare-to-best algorithm. The Main.m function calls BNS SDK functions inline.
deleted weightingMatrix2.m
1.renamed weightMatrixCircle.m to spot.m.
2.spot.m generate a spot with x offset and y offset.
2.renamed wieghtMatrixDistance.m to distanceFromFoci.m
3.moved spot.m, distanceFromFoci.m, and gauss2D.m to directory weightFunction/
4.deleted WeightingMatrix.m because distanceFromFoci does the same thing.

 deleted WeightingMatrix.m because it is the same as what now
deleted gauss2D.m, weightMatrixCircle.m, and weightingMatrixDistance.m.
Moved getImage into  imageAcquisition/ and loadFocusEfficiency.m into dataAnalysis/ with the new name plotData.m
