**Purpose**

Takes any dataset that conforms to the fasta format and normalizes it so that all lines of sequence except the last line per named sequence are of the same length.

  LINE_LENGTH=Integer           The line length to be used for the output fasta file.  Default value: 100. 
  
  TRUNCATE_SEQUENCE_NAMES_AT_WHITESPACE=Boolean
                                Truncate sequence names at first whitespace.  Default value: false. Possible values: {true, false}
