This class is used for objects that are returned by freq.analysis.
langA character string, naming the language that is assumed for the analized text in this object.
TT.resA data.frame with a version of the fully tagged text (like TT.res in class kRp.tagged,
plus frequency data).
descA list with detailed descriptive statistics on the analyzed text.
freq.analysisA list with information on the word frequencies of the analyzed text.
Should you need to manually generate objects of this class (which should rarely be the case),
the contructor function
kRp_txt_freq(...) can be used instead of
new("kRp.txt.freq", ...).
