Naming of arguments

[RobinHankin]

In the package functions, spray objects are pretty consistently denoted S. But kform and ktensor objects are less consistent. I have been using notation consistent with whatever textbook I was using at the time, but this leads to inconsistent argument naming. Here is a compilation of argument names, arranged by manpage:

Rdfile		kform	ktensor
stokes-package  "various" "T1 T2"
contract        "K"     NA
hodge           "K"	NA
kform           "S"	NA
issmall         "x"	NA
keep 		"K"     NA
Ops.kform 	"e1 e2" "e1 e2"
symbolic 	"K"	"K"
transform 	"K"     NA
is.volume 	"K"	NA
wedge2 		"K1 K2" NA
Alt 		NA	"S"

(NB: this table is edited from time to time as I modify the package)

in scalar.Rd we have is.scalar(x) which I think is OK because the argument might be a kform or a ktensor. Perhaps M would be better because both kforms and ktensors are multilinear maps.

[RobinHankin]

OK so the best I can come up with is this: S for spray objects, K for kforms, U for ktensors, M for multilinear maps that can be either ktensors or kforms. I will try to use these unless there is a good reason why not (e.g. Ops.foo(), where e1,e2 is universal.

fixed in commit 9e00f23 (the commit message was "fixes issue #27" which did not close the issue).

Quite a lot of docs use omega but I am not sure if this is OK or not
