Word Frequency Analyser

Paste the contents of a plaintext document into the main multiline text box, click "Parse," and this program creates an array for each unique word and the frequency at which the word occurs in the string. I made this to check my own writing for over-used words; if you're a writer you may notice how you tend to use the same words over and over again; in conjunction with a thesaurus this could be a powerful tool to liven up your use of vocabulary.
