New model class
+ first jot of Nuc model
some progress towards vector-based Nuc model
NucModel data c'tor testable
NucModel c'tor and probOf tests ok.
Instance of Binary for NucModel (not tested yet...)
NucModel Binary RW test ok
scoreSeq tests ok
started porting Align to new model
towards new-modeled Align (but not quite there yet...)
did away with current version of ScoringScheme
added 'modLength' function to CladeModel
Align.hs now compiles, 1 test passes
4 tests ok (nuc); protein for later
scoring scheme now a parameter, but w/o polymorphism
default scoring scheme: tests ok
Scoring scheme map can be derived from model's absent-residue score
started rewrite of Newick parser
Newick parser ok again - uses String, though
NewickParser parses String, but produces Data.Tree Data.Text
