some problems in python

[DeokjinLee]

Hello, Prof.Hwangbo.

Thanks for providing an amazing simulator.
There are 2 problems using python.

1. Getting end-effector position
   I want to use getFramePosition(~, ee_pos) function but got an error due to 'ee_pos' (I guess).
   In c++, ee_pos should be defined as raisim::Vec<3> ee_pos. Then, in python, how should it be defined?
   I tried ee_pos = np.zeros(3) / ee_pos = raisim.vec<3> etc ... but all didn't work. ​

2. Importing xacro file
   I tried importing xacro file as below but it didn't work.
   Robot_xacro_file = '~/rsc/iiwa/iiwa14.urdf.xacro'
   robot = world.addArticulatedSystem(robot_xacro_file)
   Can you provide code for this?

3. Raisim python example
   I've referring to Brian Delhaisse' github (co-developer of raisim).
   If there are more resources, please let me know.

Thank you.

1. it should directly output the position. The error message should tell you what you should do
2. Xacro is not supported
