Take it or leave it.

When I run the Check on my computer, nothing errors out on the parameterCdFile (using ::). Also, for build_data, I added another way to do it, but seeing what it does, I wouldn't do either method in my humble opinion. Just add that list to a data object, or sysdata.rda, or whatever we decide is the best.
the same file should be checked for `file.exists` that is sourced. On my comp, for example, ```R '~/Documents/R/mda.streams/inst/init_data.R' ``` exists, but ```R system.file("inst", "int_data.R", package="mda.streams") ``` does not. Also, files in inst are blown away on build. 

What I did here is kind of a stop gap solution. The file exists for package developers (and on version control), but not for users installing the package. I want to know *how* I should do this in the future, so this is a temporary fix. Someday I'll figure it out.
