Issue with unit test

[GaryBAYLOR]

Please check unit test functions as when I run devtools::test() it returns the following error and warnings:

@GaryBAYLOR - sorry about this. I believe this is because I removed sl3 and the other algorithm packages from the namespace and forgot to include these as libraries in the test scripts. I'll update and check.

@GaryBAYLOR - Running check now should return only 3 warnings that I'm trying to resolve. But there should be notes or errors now.
