Adding images to the wiki section

[vidhya001]

I have gone through the wiki section of the FLINT repository. It gives an understanding of the concepts such as pools, operations, modules, simulations, local domain, about the data types and how there are used inside FLINT.

After going through it, I got a suggestion to add some pictures in the wiki section visualizing different things that were explained in the wiki. Visualizing them either in terms of flow charts or tables etc would help anyone to get the things more effectively and understanding easier.

I would like to work on this issue. I have added a picture in the 1.1-Pools.md section. I have already done some pictures which you can see here. These images are some examples for understanding. I would like to add similar images for making the wiki visualizing better, If there are any suggestions I would be happy to hear those.

Great diagrams, thanks for doing those! there's a small typo in the last one (Rester -> Raster). Happy for you to to continue working on more of these unless @aornugent is aware of anyone else already doing the same thing.
