- Added several functions, including some xtable methods and the RSQLite wrappers
- Added dbGetColnames to get column names from a SQLite table
- Added to dbWriteFactorTable the ability to append a data.frame whose columns are a subset of the SQL table being added to.  Next step: add superset of SQL table's columns.
- Added to dbWriteFactorTable the following functionality:
    * Handles situation where the input data.frame is missing some columns that are in the SQL table
    * Handles situation where the SQL table is missing some columns that are in the input data.frame (not yet confirmed working)
- Bug in superset for dbWriteFactorTable has been fixed.  Tested working.
Added full examples to dbWriteFactorTable
- Fixed isOneSided bug. Changed to use the sides() function and fixed that function.
- Moved RSQLite-dependent functions to RSQLiteAddons.R.  Should move them to their own package eventually.
-- General package maintenance --

- Added some suggests to DESCRIPTION
- Split off RSQLiteAddons.R from Rfunctions.R
- Added appropriate handling of appending to factor tables in dbWriteFactorTable
- Added sorting by the levelKey to dbReadFactorTable.  This ensures that even if the SQL database scrambles the order of the factor tables, the reference category remains the same.
Made changes proposed by Paul Murrell:
https://github.com/gsk3/taRifx/issues/1

I.e. changed:
unit(x.range,"native")
to just
x.range
- Fixed duplicate package listings in Suggests.
- Finished fixing Paul Murrell's note about grid's native units having changed.  It was returning an error after the fix because it was subtracting a now unitless object from a unit with point.
- Submitted to CRAN as version 1.0.6
Moved AMT functions to their own package
Various changes in preparation for package release.
