Adding ff to web documentation. Part 1: cone and pyramides
The following hard particles form factors were added to web documentation ( issue #236 (closed) ):
- bipyramid4
- cone
- pyramid2
- pyramid3
- pyramid4
- pyramid6.
Using just pyramid2
( issue #244 (closed) ) doesn't work for me.
Cross-links still have the form /py/sample/particle/ff/hard/pyramid2
I'm sorry for adding several form factors in one commit, it would be more accurate do add them one by one.
