"Execute a library-of-babel block.
These blocks do not have their own body. Instead they use
a :srcname header argument to reference a different source
block, whose body they use. Source blocks in the library of
babel should use a standard naming scheme for the variable
containing the input data for analysis / plotting. E.g. if that
variable is always called __data__ then one of these bodyless
babel blocks will call a library of babel block using :var
__data__=<some reference>. The header args from a babel block
are appended to the header args from the target block.
This function is called by `org-babel-execute-src-block'."
