begin coding real initSwirl, saveProgress
minor
userProgress.R in progress
semi-operational user progress save/restore;
a couple of bugs to fix.
fixed initSwirl.default to allow course names other than "4Daphne"
Merge branch 'master' into feat.UserProgress
Fixed bug which prevented restoration of user-defined variables. Sync'd branch with updated master--coursenames besides 4Daphne now permitted.
Completed modules recognized and indicated by renamed progress files.
create user_data directory if not present, using recursive=TRUE flag in dir.create
Merge branch 'feat.UserProgress' into swirl1_incorp
apparently "successful" merge of swirl1_incorp and userProgress branches
