# This is alternateive from glue: worth providing?
# Enforces a maximum width of a string inside an
# html container. If the string exceeds this maximum width
# the string gets wraped.
#
# Not really useful, better use the CSS overflow: hidden
# functionality.
#
# === Input:
# the string to be wrapped
# the enforced width
# the separator used for wrapping
#
# === Output:
# the wrapped string
#
# === Example:
# text = "1111111111111111111111111111111111111111111"
# text = wrap(text, 10, " ")
# p text # => "1111111111 1111111111 1111111111"
#
# See the test cases to better understand the behaviour!
# def self.wrap(string, width = 20, separator = " ")
# return nil unless string
#
# re = /([^#{separator}]{1,#{width}})/
# wrapped_string = string.scan(re).join(separator)
#
# return wrapped_string
