straw dog for access pattern

added readr >> read_tsv

Make a consistent naming convention when dealing with reported columns.

Roxygen update.

Remove long running WQP test

Took out a loooong running test. It is a known issue from the WQP, not worth the time to always test here.

Incomplete dates

New way to deal with incomplete dt columns. Leaving the NA's as they come, and adding a date column.

Better encoding and starting switch to dplyr

Fixes #140. So now, if a column that is modernly displaying date and time, it still gets returned as a POSIXct dateTime. If some of those columns are only dates, a time of noon...with the median time zone offset...is added, and a new column is created to indicate a TRUE/FALSE date flag.
