Credits/sources

The functions in the package are to some extent re-writes of stuff I had found online and or a function that is now available in a package rather than having to search the web. E.g. I added the currency capability to the number_formatter() function, which in turn is based on the f2si() function from the sitools package and this stackoverflow post with minor changes, such as the currency. https://stackoverflow.com/questions/11340444/is-there-an-r-function-to-format-number-using-unit-prefix/29932218

The suffix_formatter() functions are based on this stackoverflow post https://stackoverflow.com/questions/28159936/formatting-large-currency-or-dollar-values-to-millions-billions Again currency functionality was added.
