Shugeo suppression overlaps (#9) * Added non_max_suppression_overlaps op and tests. * Refactored implementation of non_max_suppression_overlaps. * Refactoring of implementation of non_max_suppression_overlaps op. * Refactoring of implementation of non_max_suppression op. * Fixed portion error. * Added cuda frontends for image suppression ops. * Eliminated crash with cuda arch on image.non_max_suppression_overlaps op. * Improved implementation of image_suppression helper for cpu platform. * The generic approach of non_max_suppression_overlaps op helper with cuda platform. * Working cuda implementation of helper non_max_suppression_overlaps op. * Eliminated waste comments. * Improved implementations for both platforms * Refactored cuda implementation of image.non_max_suppression_overlaps op helper. * Improved cuda implementation of non_max_suppression op helper. * Refactored cuda implementation of image.non_max_suppression_overlaps op helper. * Improved cuda implementation of image.non_max_suppression_overlaps op helper. * Added modifications into cuda implementation for image suppression overlaps op. * Correct queue emulation with cuda implementation of non_max_suppression_overlaps op. * Prefinal stage of cuda implementation of non_max_suppression_overlaps. * Worked cuda implementation of non_max_suppresion_overlaps helper. * Fixed return to proper thread. * Improvements for cuda implementation of image.non_max_suppression_overlaps op helper. * Fixed implementation issues with non_max_suppression_overlaps on cuda platform. * Fixed skip for non_max_suppression_overlaps on cuda platform. * Finalize implementation of image_suppression helper and tests. * Cosmetic changes only.
