## org.biojava.bio.program.blast2html
Class AlignmentMarker

    java.lang.Object
      org.biojava.bio.program.blast2html.AlignmentMarker

    public class AlignmentMarker

extends Object

Class to do simple HTML colouring of sequence alignments.

For any particular alignment position, the colouring depends only on the two characters at that position. The decision is made in two stages:-

1. Whether to colour or not in the `ColourCommand.isColoured()` method
2. what the colours are in the `AlignmentStyler.getStyle()` method

This allows simple choices to highlight the mismatches, the identities or simply colour up everything.

The current implemention of step 2. is a simple colour lookup.

Limitations:

As the FONT styles need to be defined before being used in the HTML, it means the all colours to be used have to calculated up front.

The position in the alignment is not passed in so position dependent colouring ( say against a HMM profile ) would be involve either changing the interfaces or implementing them such that they knew the required information via another route.
