Presently, pvget takes only pva PVs (not ca), but can do monitor and put.
Conversely, eget can take PVA PVs or CA PVs, but cannot monitor and there is no eput.
This makes it difficult for a user to keep up and remember when they need to
do what. Suggest we have all 6 of these below.
pvget -m pvapvname
pvput pvapvname value
eget pvapvname | capvname
eget -m pvapvname | capvname <- NOT YET IMPLEMENTED
eput pvapvname | capvname value <- NOT YET IMPLEMENTED
