Actual data extraction. The template parameters are neccessary because we have to handle multiple unrelated record types and call member functions of varying return type, but note that they don't need to be specified in practice because the rawFunctionPtr parameter defines them anyway.

Parameters:

iEvent	The event to get the records from.
allPatterns	Destination object
label	First half of the input tag that identifies our source in the event
instance	Second half of the input tag that identifies our source in the event
rawFunctionPtr	Pointer-to-member-function that specifies a getter function that extracts the information we want from the record object.
prefix	The column name prefix that defines how the columns in the pattern map will be named (

See also:

L1GtPatternLine::push)

Parameters:

packingFunction

an optional function that the raw value is passed through befor it is added to the pattern line
