The patch is committed, but we can refactor later if we need to.
Indeed. I expect this to be a somewhat fluid interface for a while -
maybe we need to toss a libmesh_experimental() warning in there
somewhere?
For instance, after discovering that ',' made a lousy delimiter
between vector components (at least if you don't want to also
inadvertently disable non-unary functions) in my first version, I'm
now discovering that '#' makes a lousy delimiter too (at least if you
don't want hairy interactions with GetPot comments).
At this point I'm leaning towards hideous syntax like:
function_list = '0 {1} {cos(x)}{sin(y)}'
for putting lists of functions (in this case: two scalar-valued, braces
optional; one vector-valued) into GetPot. And best not to let any
spaces slip into your functions, because GetPot doesn't skip even
quoted spaces as a vector-of-strings delimiter...
