Merge branch 'develop' into feature/gui
I have attempted to apply the folder/file name changes from develop onto the GUI branch. I have messed something up.  The gui runs but it ony allows for a generic network, so something is not import correctly.
I think I fixed that issue Harold had.
Added IP algorithm to the GUI.
Setup of algorithms.rst file for other's to added their documentation
added file poreproperty.py which gives the user an opportunity to add inlets and outlets (currenly only used by IP) to the network.
Committing __Import__ file early on, so that I don't make the same stupid mistake again of not selecting it
Tiny update to call of OrdinaryPercolation
Code written, just debugging now.
