Cista

[cflaviu]

Hi, I just come across to this repo and it seems to me the library's goal was also achieved by Cista.

[Tradias]

Heya, I believe the design goals of the two libraries are a bit different, but I guess cista can be used to achieve a similar memory layout compared to this library.

I believe a closer comparison to contiguous would be https://github.com/brenoguim/flexclass.

Not sure whether I have used cista correctly and it certainly would be more cumbersome to append new elements to the contiguous vector e.g., but the numbers look good for it: (you can see the code here)
