plotProteinSeq draws the sequences of proteins within the same "ProteinSeq" object. In this format, more similar sequences will have
similar banding patterns.

A draw of the protein sequence(s) provided. Colors refer to specific amino acids ("R", "W", "I", "F", "S", "T", "N", "H", "K", "D", "G", "L", "Y", "V", "M", "A", "E", "P", "Q", "C")", "gaps/space in the sequence ("-"), ambiguous amino acid ("B" - often representing either asparagine ("N") or aspartic acid ("D")), or another marker for ambiguous amino acid ("X").
