Overall continued package name change by changing namespaces from industrial_filter to industrial_pcl_filter everywhere.
Added a configuration file, for custom dynamic reconfiguration (instead of pcl_ros FilterConfig).
CMakeLists.txt- added two lines for making config files.
...nodelet.cpp - replaced generic FilterConfig with ConcatenateMLSConfig, added new config params in config_callback.
...mls.h - added getter/setter for search radius.
...nodelet.launch - added two passthrough filters.
