Cyclus [Toolkit page](https://github.com/cyclus/cyclus.github.com/blob/source/source/arche/toolkit.rst) is missing information on - [ ] Material Buy Policy - [ ] Material Sell Policy - [ ] Total Inventory Tracker - [ ] Res Manip - [ ] Timeseries Buy/Sell policies might warrant their own page linked from within the toolkit page? Also the archetype development tutorials ([C++](https://github.com/cyclus/cyclus.github.com/blob/source/source/arche/tutorial_cpp/toolkit.rst), [python](https://github.com/cyclus/cyclus.github.com/blob/source/source/arche/tutorial_py/toolkit.rst)) should probably link to the main toolkit page
