New Functionality:

 Yosef started to review Kuibit , he was able to generate some images but he encountered some examples missing found in the documentation notebooks (development version) and some python dependencies failed to build in his machine.  Yosef does not know what task he should be performing: [RH] 1. reviewing the code base for Kuibit but might not be necessary because it has been already reviewed by an open source reviewer. [RH] 2. Check if the installation instructions and user manual fulfill their purpose.  [RH] Decide how to install, adding it to getcomponents or use the same method SefForce-1D code uses. 
Gabrielle Bozzola explained that he can tag the documentation for each of Kuibit versions to avoid mixtures. Gabrielle also mentioned that installing Kuibit with pip should be enough to get all the dependencies necessary to successfully install and run it. 
Gabrielle could fix the mixed documentation and that the missing examples was a glitch, should be fix. he will work on this. 

Roland suggested that having  instructions to generate the BBH gallery example plots with Kuibit should be enough and users should be referred to kuibit documentation if they want to explore more Kuibit capabilities.

RePriMand: Roland has started checking it, recreate the example provided by Wolfgang , he created a make file  and it works.  He also created a thornlist  that gets it as an external library. 

FLRWSolver: no update. [RH] will contact the people in charge through the ticket. 

[RH] Ideally, the reviewed inclusions should be added before the release freeze (Nov 12). 

Unanswered question on mailing list:

[SB]: Hee II responded, precise math did fix the issue (intel NaNs vs  no NaNs gcc). Steve is going to investigate more about this.
