use lapply() instead of sapply(), and we have to check if x is really a qt layer before we set limits
a first attempt to clean put the map code

- #' instead of ##'
- 2 spaces indentation
- tidy up other weird code structures

it is not done yet; this big function must be decomposed at some point
make sure the example code can be wrapped < 90 chars, as required by R CMD check
Recall is safer than the hard-coded function name
reformat the code for qparallel()
clean up examples and synchronize documentation (roxygenize)
why do we need the reshape package at all? it is not used anywhere
avoid partial matching argument: mouseMove -> mouseMoveFun
use library() instead of require(), because require() does not stop() if package does not exist
these small helper functions should not be formally documented as roxygen comments, which will eventually generate Rd files
suggests knitr for qsave_knit(), so that R CMD check does not complain
fix the brfss example
argument d -> direction; avoid partial matching
because productplots is not imported, we need the ugly :: operator for now
the qtime() formula interface does not work; @chxy should take a look at this problem
clean up the nasa example, and include it in ?nasa
bump version; there are still several problems revealed by R CMD check, and I have not managed to fix all of them

for now, @chxy should check the examples in ?pigs
