User-friendly functions for extracting a data
table (row for each match, column for each group)
from non-tabular text data using regular expressions,
and for melting columns that match a regular expression.
Patterns are defined using a readable syntax
that makes it easy to build complex patterns
in terms of simpler, re-usable sub-patterns.
Named R arguments are translated to column names
in the output; capture groups without names are used
internally in order to provide a standard interface
to three regular expression C libraries (PCRE, RE2, ICU).
Output can also include numeric columns via
user-specified type conversion functions.

RE2 engine (re2r package) was removed from CRAN in Mar 2020
so must be installed from github.
