mdatools v. 0.3.0

• PLS and all related methods were rewritten from the scratch to make them faster, more efficient and also to follow the same code conventions as previously rewritten PCA. Here are the main changes you need to make in your code if you used mdatools PLS before: selectNumComp(model, ncomp) instead of pls.selectncomp(model, ncomp), test.x ad test.y instead of Xt and yt, finally separate logical arguments center and scale are used instead of autoscale. By default scale = F and center = T.
• PLS and all related methods are now well documented (see ?pls or ?mdatools)
• plotting tools for all classes and methods were rewritten completely. Now all plotting methods use either mdaplot or mdaplotg functions, which extend basic functionality of R plots. For example, they allow to make color groups and colorbar legend, calculate limits automatically depending on elements on a plot, make automatic legend and many other things.
• many small improvements and bug fixes
