[r-t] Multi-extent 5-part Surprise Minor

[John Warboys]

I have added a few more compositions to my website
http://website.lineone.net/~jswcomps as follows:

SU0722 - 5040 incorporating some 'single-change' methods to get the maximum
of 42 methods

SU0304 - 2160 containing 14 Carlisle-over and London-over methods from the
standard 41
SU0405 - 2880 containing 21 Cambridge-over and Norwich-over methods from the
standard 41

SU0406 - 2880 containing all 17 Carlisle-over and London-over methods from
the standard 41
SU0503 - 3600 containing all 24 Cambridge-over and Norwich-over methods from
the standard 41

SU0304 and SU0405 together allow 35 methods from the standard 41 to be rung
all-the-work bobs-only in 5040 changes, the previous maximum for this was 29
methods.

SU0406 and SU0503 together allow all 41 standard methods to be rung
all-the-work bobs-only in 6480 changes (9 extents).

I haven't yet considered Ander's suggestions for just 4 changes of backwork
per part or 4 separate 5-part blocks but will do so in due course.
