Added stats_t structures to summarize dive statistics by depth and by temperature. Process each dive to add the dive stats to the proper depth and temperature bucket. Buckets are defined using constants STATS_MAX_DEPTH, STATS_DEPTH_BUCKET, STATS_MAX_TEMP, and STATS_TEMP_BUCKET which are defined in statistics.h Signed-off-by: Doug Junkins <junkins@foghead.com>
