# String inflections define new methods on the String class to transform names for different purposes.
# For instance, you can figure out the name of a table from the name of a class.
#
# "ScaleScore".tableize # => "scale_scores"

# Returns the plural form of the word in the string.
#
# If the optional parameter +count+ is specified,
# the singular form will be returned if <tt>count == 1</tt>.

# ==== Examples
# "post".pluralize # => "posts"
# "octopus".pluralize # => "octopi"
# "sheep".pluralize # => "sheep"
# "words".pluralize # => "words"
# "the blue mailman".pluralize # => "the blue mailmen"
