Approx String Match & Interface to Other ggplot2 Extensions

Major Updates

Approximate String Matching

• Approximate String Matching reduces programmer's stress because
  we usually type tokens only by its consonants.
  • aesthetics (size by sz)
  • theme configuration (legend.key by l.key, or legend.box.background by l.b.b)

Interface to other ggplot2 extensions

• The main scope of ggbash is to make a compiler for default ggplot2 functions.
  Handling ggplot2 extension libraries within ggbash() arguments
  should increase complexity
  and might significantly slows down the development process.
  As a remedy, ggbash() now returns a ggplot2 object (not a string) by ggbash(),
  and can chain other geom_ or theme_ objects by the normal + operator in ggplot2.
  • Ex. ggbash("gg(iris, Sepal.W, Sepal.L) + point(col=Spec, size=5) ") + geom_text_repel(aes(label=Species))

Bug Fixes

• add docs tests of various geoms
