check for CATKIN_ENABLE_TESTING
Added support for YAML-CPP 0.5+.

Merge pull request #146 from DLu/hydro

Updates from Groovy Branch
costmap_2d: fix (some) memory leaks using boost::shared_array for dynamic allocations
costmap_2d: use std::fill_n instead of memset to initialize arrays

memset corrupts the heap as a bool array of size n has a size less than (n * sizeof(bool)).
