/*
A simple driver for testing paraglob's performance and functionality.
Supports the following arguments:
-b <a> <b> <c> <time> -> Benchmark paraglob. See below.
-n <text> <patterns> -> Print the number of matching patterns in the text.
Benchmarking:
a -> number of patterns to generate
b -> number of queries to perform
c -> percentage of generated patterns that match queries
<time> -> optional. If provided, rather than printing detailed results,
prints 1 or 0 corresponding to rather or not the benchmark was
completed in under <time> seconds
Note that this script is just for testing and as such if you give it bad
arguments it will ungracefully break.
