This package is the equivalent of the text information gathered here. I did not create the code in this package rather I found that this was the most accurate source for verifying types at runtime that I could find and put it in package format so that other's could use it in their programs if they wanted w/o having to look-it-up everytime. The code is still open source with an ISC license for everyone!
