Changes made mostly to applyFilter and src/nodes/.cpp - changes made while troublshotting to make code not only build properly, but functional. Likely still need to check full functionality, but good state to commit.
Added launch file for testing concatenating and MLS node. Changed include file to make two members more generic. Changed src/concatenate_mls.cpp to use += instead of concatenateFields. Minor edits to src/nodes/...test.cpp, including more ROS_INFO statements.
Added launch file for nodelet testing. Will need to add own cfg file to dynamically configure more relevant params. Simplified CMakeLists to have one library. concatenate_mls.h: Added inline to methods and added new params to specialization template for <sensor_msgs::PointCloud2>, and used PCL_INSTATIATE. concatenate_mls_nodelet.h: Just corrected misspellings. nodelet_plugins.xml: corrected spelling. concatenate_mls.cpp: added constructor, destructor and applyFilter methods for nodelet to function, also added PCL_INSTANTIATE. concatenate_mls_test.cpp: minor edits involving consoldating and moving declarations up
minor edits to test.cpp file involving consolidating and moving declarations.
Major change - changed package name to industrial_pcl_filters to be more unique
minor changes in manifest to reflect package name change.
