  evigene/scripts/genoasm/asmlink2refchr.pl
  
  chromosome level scaffolding for chr assembly, using ref chr assembly
  based on chromonomer, with alignments to ref chrs from blastn asm x refchr
  
  includes asm contaminant screen, given contaminant.seq data
  uses gene align table, to keep contigs w/ valid genes
  uses dna cover depth table to classify duplicate contigs as valid or not (from gnodes analyses)
  
  without contam.seq, or gnodes.covtab, or gene aligns, 
    a. links asm contigs to ref chrs, placing all alignable contigs to closest ref chr locus
    b. retains all duplicate region contigs, 
  ie. contigs should be pre-screened or screened here w/ dna depth, contam, genes, to separate
     valid/invalid redundancy
