New parameter functions + files renamed and splitted.
Some corrections to the new parameter functions.
Added documentation for the new functions.
Version change to 1.3.3
Fix a small problem with rTTaxo() introduced by the last changes.

the default for format in rTTaxo is no longer "peptide", it is NA, and
no warning will be generated by NA. (This allows to use rTTaxo without
data.)
Corrected k-score functions and added hrk-score (based on TPP).
Version change to 1.3.4
