#138 no need to repeat the some on.exit exp every time
updated roxygen
Revert "Travis build fails on time-out. Reducing test replications to 5 (down from 10). #141"
Can't weaken testing to please travis or CRAN. That's the rule
This reverts commit 09caa2c14705e5301493be8dece157a822523f6e.
Travis doesn't allow thorough testing and has been a pain all along and encourages people to commit without testing. Killed.
