getnestedfield

Use a regular expression to find a (potentially nested) field in a structure and return its contents.
USAGE: F = getnestedfield(S, EXP)
INPUTS
S: The struct to search
EXP: Pattern used to find field (passed to REGEXP)

OUTPUT
F: Field contents. If no fields are found, is an empty array. If multiple fields found, is a N x 2 cell array where N is the number of matching fields, first column contains full locations of each match, and second column contains their values (this is raw output from NSTRUCT2CELL, see CREDIT below).
