LutBuilderaT  A class for building a MorphLut from a descriptive language

    The input patterns is a list of a strings sequences like these::

        4:(...
           .1.
           111)->1

    (whitespaces including linebreaks are ignored). The option 4
    describes a series of symmetry operations (in this case a
    4-rotation), the pattern is described by:

    - . or X - Ignore
    - 1 - Pixel is on
    - 0 - Pixel is off

    The result of the operation is described after "->" string.

    The default is to return the current pixel value, which is
    returned if no other match is found.

    Operations:

    - 4 - 4 way rotation
    - N - Negate
    - 1 - Dummy op for no other operation (an op must always be given)
    - M - Mirroring

    Example::

        lb = LutBuilder(patterns = ["4:(... .1. 111)->1"])
        lut = lb.build_lut()
