I don't think you need this PR too, you can combine them into one here
https://github.com/DataIntellectTech/TorQ/pull/755/changes

You can also remove the file from this PR where you just have some placeholder code

Hi Cormac, I have combined the "Enable Gateway to Read Cache" and "Enable Gateway to Request Cache Asynchronously" PRs into one PR here. I have also removed the getter.q file containing placeholder code from the "Add cacheConfig, setter process, getter script" PR. I have also addressed your other comments.

Hi Cormac, thank you for reviewing and your comments. I have uploaded a template cacheconfig.json file containing configurations for the Anycache system. The cachename and asyncprocessname is now part of the cacheconfig.json file so there is no need to pass them as parameters to functions.
