Added a new set of simmechanics files with no arm.

New CAD file and simmechanics files with no arm and more clear
link names. This should make it easier to generate a URDF.
Updated fixed fram no-arm CAD files and simmechanics files.

Broke out the wheels and casters in the base model instead of
using a sub-assembly because the simmechanics file generated
would create a messed-up URDF in which there was one caster with
two links to it from the base.

Base now has caster and caster wheel as parts in it instead of a
sub-assy.
Abby's URDF is looking pretty good.

This URDF looks good in the graph visualizer (no arm). I need to
change the joint defs for the casters and wheels so they can turn
and will probably need to make some tweaks when I load this in rviz
and gazebo. Then I'll need to add the arm w/ the xacro macro.
Added setup script for installing moveit.
Updated files for no arm urdf generation and removed generated urdf.
Added some reference papers.
Cleaned up more urdf and yaml files.
Added more stuff to moveit installer.
Updated some CAD files.
Kinect bracket designs.
Updated CAD files.
Merge branch 'master' of github.com:evenator/masters

Conflicts:
	CAD/Invacare/invacare assy.iam
Updated CAD files.
Added IRB 120 references.
Added gripper and bin.

Changed gripper plate thickness to reflect wooden prototype pieces and
removed gripper jaw extensions. Generated gripper simmechanics files.
Created bin and regenerated robot simmechanic file and STLs to include
bin.
Added festo solenoid valve datasheet to references.
Ros setup script edited to include rosserial install.
Added a figures directory.

Includes a few pictures I took and the kinect's unregistered view.
Renamed CAD to Mechanical and PCB to Electronics.

Also created block diagrams of the power and data connections and
created a schematic of the gripper solenoid/arduino setup.
Added spike and sick lidar datasheets to reference.
