[r-t] Update on jump methods

[Tim Barnes]

Under the Framework's retroactive recognition provisions, the CC Methods
team is in the process of adding methods to the Methods Library that were
rung and named in the past, but which did not qualify for inclusion in the
Library at the time.  Over 700 such methods have been added so far -- a
listing is available here:

https://complib.org/report?name=retroactiverecognition

The requirement for retroactive recognition is that a method was rung in a
performance that would have qualified it for inclusion in the Library had
the Framework been in place at the time of the performance.

One set of methods we're working on adding to the Library are those that
include jump changes.  The table below shows the jump methods we're aware
of, many of which were rung by members of this list.  There are a few open
points as shown in the Comments column.  If anyone can provide any info on
these, please let us know either via this list or at methods at cccbr.org.uk.
Please also let us know if there are any other rung jump methods that
should be added to the Library.

The Framework classifies any method with jump changes as "Jump", and Jump
is included in the method's title.  So, for example, Cambridge Treble Jump
Minor will be given a method name of "Cambridge Treble", it will have a
classification of "Jump", and so its title will be "Cambridge Treble Jump
Minor".  This gives sensible results for all the methods below, with the
possible exception of Jump Stedman Doubles, which would become Jump Stedman
Jump Doubles.  We've reached out to the band that rang this to see if they
would like to rename it.

The other question that arises in adding these methods to the Library is
how to notate jump changes.  I'll send another note shortly that has the
Method team's proposal on this (and which explains notations such as (24)
below).
