Add `ezknitr` to cedta.pkgEvalsUserCode

[mattmills49]

ezknitr is a package that helps with using knitr's knit and spin functions that I use frequently in combination with ProjectTemplate project directories. When using the data.table package in my scripts I received the "cedta decided 'ezknitr' wasn't data.table aware" message when attempting to spin the script with the datatable.verbose option set to TRUE. I was able to fix this by running the assignInNamespace("cedta.pkgEvalsUserCode", c(data.table:::cedta.pkgEvalsUserCode,"ezknitr"), "data.table") command but was wondering if ezknitr could be added to the default packages to be excluded in the cedta.R file? If not then that's fine, at least I know how to avoid this error in the future.

Many thanks. Yes will add.

Any idea why ezknitr was created rather than enhancing knitr? I looked at the Description for ezknitr and that's what struck me. I asked here: ropensci/ezknitr#13
