ParsedVectorReporter

Apply parsed functions to vector entries held in reporters.

Overview

ParsedVectorReporter operates on the elements contained in series of vector reporters using a parsed function expression as shown in Listing 1. This reporter allows several vector reporters to be combined into single vector. This reporter operates on multiple vectors of the same size and returns a vector of that size. There must be one "reporter_names" for each "reporter_symbols". This is a vector version of the ParsedScalarReporter reporter.
