fix out of bounds, change some defaullt const
remove debug printlns
Column encapsulate code in updateSynapses()

just cosmetic change, better for debugging code
make inhibitionRadius float

so it can change slowly, if int, rounding error stopped any progress there

needed to add set/get-InhibitionRadius methods
SpatialPooler: make neighbors() return List<Column>

instead of index of neighbor
small speed up for neighbors
separate functionality neighbors() and getSortedOverlap()
small fixes
keep inhibitionRadius in reasonable range

setInhibitionRadius() to crop it between 0..Max(dimX,dimY)
tune java runtime flags for parallel performance and memory
Main new class for parallel testing
use Collection where possible, instead of List

for I plan use HashSet later
