assign_icd_data: Assign all the data in the package to the calling environment
Description
Used by icd to load all the data into its environment. This should not
be needed by most users, who can simply refer to the data objects normally
after calling library(icd.data).
# NOT RUN {assign_icd_data()
# but really all most users need to do is:library(icd.data)
# then refer to the data in the package in the normal way:print(icd10_chapters)
# }
