### Regular Expression ###
##########################

# Ruby is very good at dissecting data.  The reason for that is that Matz
# elected to not only include a mini language used for pattern matching, but
# more importantly to treat it as a first class citizen inside Ruby.  This mini
# language is called Regular Expression.

# There are many advantages to learning to use Regular Expressions.  Some tasks

### Regex ###
#############

# Build regular expressions to match each of the following:
# 
# 1.  An IP address.  Use the format N.N.N.N, where each N is an Integer between
#     0 and 255.  Don't allow numbers outside that range.  There aren't always
#     three digits either.  For example, the loopback address for your computer
#     is 127.0.0.1.
