handlr v0.2.0

NEW FEATURES

• gains function handl_to_df(); converts any handl object (output from HandlClient or any *_reader() functions) to a data.frame for easier downstream data munging; HandlClient gains $as_df() method which runs handl_to_df(); to support this, now importing data.table package (#15) (#19) feature request by @GeraldCNelson

MINOR IMPROVEMENTS

• now exporting the print.handl method. it only affects how a handl class object prints in the console, but is useful for making output more brief/concise (#14)
• filled out a lot more details of what a handl object contains. see ?handl for the documentation (#17)
