This is a class I haven’t talked about here, and for good reason, it was way to simplistic. Initially all this class did was scrape use the bls.gov inflation calculator and return the results. This however is slow, sometimes very slow, and I grew tired of waiting for it. With this update it now does the calculations locally for speedy adjustments. It also can do to-the-month adjustments now, something the bls.gov calculator does not support (even though they have all the data needed).
I know it’s a oddly specific thing to need, but if you need it check out the github repoitory.
