Add useful functions commonly used in projects

[Andrew Palfrey]

Functions such as maybe_json_decode, multi_array_key_exists and multi_array_map. multi_array_map needs to be used in the account component for an issue (see here)

We have a Class - Arrays to handle functions for arrays. Can we add the functions to that file?

[Andrew Palfrey]

For some we could, others like the maybe_json_decode I mentioned wouldn’t really work in there, since it’s not about arrays.

@apalfrey1 OK. If it is about array, we can add it to the Arrays file. If not, just add it to where appropriate. If you think we need a class for a collection of the functions for the same target, we can have a new class.

@Luke Nelson @Jamin Xu I’ve added a bunch of useful functions, check out the item in teams. Is there any others that could be added in as well?

[Jamin Xu]

@apalfrey1 @luc122c Brilliant! That will save us a lot of headache in the future. I don't have any, but I would like to have a team discussion about where to keep them.
