Two new kernels, 'Aitchison()' and 'cLinear()', for compositional data.
A new kernel, 'Chi2()', for computing the chi-squared kernel for bags-of-words.
New function, 'aggregate_imp()', that aggregates a table of features following a user-defined grouping criterion.
Minor improvements and bug fixes
'plotImp()' now throws an error when the user requests more features than the actual
number of features present in x. Also, problems when displaying the correct xlim are fixed.
'heatK()' allows the user to input a legend title.
'KTA()' now only accepts binary variables for its parameter 'y'.
