class String
# Apply a set of rules (regular expression matches) to the string.
#
# === Requirements:
# The rules must be applied in order! So we cannot use a
# hash because the ordering is not guaranteed! we use an
# array instead.
#
# === Input:
# The array containing rule-pairs (match, write).
#
# === Output:
# The rewritten string.
