abstract base class for representing scoring schemes for alignments.
- Detailed: ScoringScheme objects contain two scoring rules:
- a rule for comparing any character from a sequence to a gap character (usually liste as gap insertion and gap extension, or d and e)
- a rule for scoring two elements from a sequence (simply S) Generally the rule for scoring gaps is composed of a gap insertion and a gap extension parameter. It's important to note that alignments derived using the ScoringScheme and Aligner objects are only guaranteed to be optimal if every element of S is bigger than -2 * e.
