Simile Finder

# concept: A program which searches through a book and maps out every metaphor.
# to make this work, I'll need to find the phrases that ordinarly signal the presence of a metaphor or imagery.
# I'll need some way of indexing place in the book - line number, paragraph number, something.
# I'll need to export the results to a text file and print out some meta-information about them.
# I'll want to match nouns together, maybe, too.
