Order of operation: 1. If data was given via a string then save it to a temp file. (see setData()) 2. If the specified file is nonlocal (URL) copy it to a temp file. 3. If a preprocessor was specified, run the input file through it. 4. Read the output of the preprocessor. 5. If Uppercase was specified: Turn the read data to uppercase. 6. Write the result to a temp file. 7. If a line-matching preprocessor was specified, run the temp file through it. 8. Read the output of the line-matching preprocessor. 9. If ignore numbers was specified, strip the LMPP-output of all numbers. 10. If ignore comments was specified, strip the LMPP-output of comments.
