updated DESCRIPTION file and removed calls to source(), so we either user devtools::load_all() or just build and reload
Issue #6: Made appropriate all.equal changes.
Made .Rbuildignore ignore course modules which are in csv format, so they will not appear in the PACKAGE directory. They will, of course, remain in the PROJECT directory under version control.
Issue 7:
Combined minimulti.R and swirl1.R into swirl.R
Removed cruft from all .R files
Made former swirl1 methods the defaults
Renamed "hi" to "swirl"
Adjusted description file: added pwr package to eliminate initModule.R for one module
Updated commentary
