CALL: GET_HISTOGRAM
The histogram is referenced via a global variable that has usually
been returned by a call to BOOK_HISTOGRAM.
The name of the Garfield library from which the histogram should be
read.
The name that has been given to the member in the Garfield library
that contains the histogram. If the member name is omitted, then
the a member with the name of the global variable to which the
histogram is to be assigned, will be searched for.
This is in many cases a meaningful default and there is therefore
rarely a need to specify a member.
