* initial version of renewed HoughCircles done

* fixed compilation

* fixed SIMD ability & compilation warning

* fixed accumulator nonmax comparison

* common Mutex for all invokers

* nzLocal is std::vector

* nz is std::vector

* SSE2 -> SIMD128

* centers is now std::vector

* circles is std::vector

* estimateRadius updated

* accum calculation w/o mutex

* less deprecated code

* several bugs fixed

* back to mutex, TLS gathering doesn't work
