- New argument text in plot0() to add centered text in the plot region.
Changes in the package structure:
- Code coverage has increased from 3% to 17%.
- pickcolors() has been renamed pickColors().

Addition of functions:
- New R functions toFig() and toFig() that allow conversion from figure region coordinates to the user coordinates and conversely.
- New R function encircle that encircles a set of points.
- New R function box2(), a flexible version of box().
- New R functions ramp(), darken(), lighten() to ease the creation of color shades.
Changes in existing R functions:
- Add the proper namespace for all functions used for grDevices and graphics package.
- plot0() now has a fill argument that calls plotAreaColor() to color the plot region.
- a vignette has been added to showcase the package.
