Delete first attempt of planners

@amdshameer, these are where you should have continued working.
Not creating new files.
I am deleting them and re naming your new test_PLANNER.py to keep your git commit history.
Otherwise it would look like you didn't do the work.

see issue mas-group/sdp_ws2013_ompl#51
Renamed planners removed test_

@amdshameer. I have removed the test_ infront of the planner nodes.

Please only work on these files and do not check in test files unless they are real unit tests.
I believe these were just you testing if it worked.
Use Git to test. create a new branch, work on the original files in the new branch and if it doesn't work, then delete the branch and checkout the master again.

This is related to comments on issue mas-group/sdp_ws2013_ompl#51
tested @amdshameers changes. fixed errors

Now it works with roslaunch
fixed the rest of the planners

removed old ros stuff
imported ompl_demo from correct location

changed launch example to launch all 4 planners.

@amdshameer there is still a bit of work to be done for issue mas-group/sdp_ws2013_ompl#51 we can discuss the rest today in the scrum.
