# Extracts an excerpt from +text+ that matches the first instance of +phrase+.
# The <tt>:radius</tt> option expands the excerpt on each side of the first occurrence of +phrase+ by the number of characters
# defined in <tt>:radius</tt> (which defaults to 100). If the excerpt radius overflows the beginning or end of the +text+,
# then the <tt>:omission</tt> option (which defaults to "...") will be prepended/appended accordingly. The resulting string
# will be stripped in any case. If the +phrase+ isn't found, nil is returned.
#
# ==== Examples
# excerpt('This is an example', 'an', :radius => 5)
# # => ...s is an exam...

# excerpt('This is an example', 'is', :radius => 5)
# # => This is a...

# excerpt('This is an example', 'is')

# excerpt('This next thing is an example', 'ex', :radius => 2)
# # => ...next...
#
# excerpt('This is also an example', 'an', :radius => 8, :omission => '<chop> ')
# # => <chop> is also an example
#
# You can still use <tt>excerpt</tt> with the old API that accepts the
# +radius+ as its optional third and the +ellipsis+ as its
# optional forth parameter:
# excerpt('This is an example', 'an', 5) # => ...s is an exam...
