@describeIn does not work well at the moment (klutometis/roxygen#309)
closes #2: make it possible to specify a custom table sketch

also closes rstudio/shiny#582
roxygenize
make sure the table is not order by the first column; I think the default behavior of DataTables that order the table by the first column is a bad idea
align numeric columns to the right (who would want numbers to be aligned to the left anyway?)
simplify examples that involve column alignment
show the 8th page so users can see the effect of abbreviation immediately
roxygenize
options$order will be list() internally if NULL
width 100% and height auto; the default size does not seem to be good
update DataTables to 1.10.4
the server mode of datatable(); it does not store data in JSON
no longer need thiz
the examples will be moved to a vignette
shiny output/render functions, per suggestion of @tareefk
use knitr for an R Markdown vignette later
roxygenize
use camelCase() consistently
camelCase for everything in this package
must not use random temp filenames, because R CMD build/INSTALL may run the code twice, and generate different Rd files for the same imported object
