Reference developer home folder

[walchko]

Suggest fixing this, there is no point to deploy code that references a developers home folder. It also happens in another place in the code.

robotics-toolbox-python/roboticstoolbox/examples/mobile.py

Line 13 in 176f21c

vars = loadmat("/Users/corkep/code/robotics-toolbox-python/data/house.mat", squeeze_me=True, struct_as_record=False)

commented out for now, but really need to develop some example scripts. Some of these are covered in the notebooks here. Data files are are now shipped with the toolbox and accessible in an installation independent manner.
