Beginning branch to format inputs to make sure they are valid values, including appending the appropriate extension to the filename
Outputs error messages for out-of-range freq and duration as well as for empty string file name. This returns with status (1) for error cases.
Program will append .wav extension for file names that are too short to validly have that extension.
I fixed an error with the compile script and updated some of the tune script
Merge branch 'scripting'
I updated the .gitignore file to ignore .diff files, .wav files, .DS_Store and some others. Also, this has the updates to the scripting branch from the merge. I deleted some of the comments in the main .c file and added Ivan to the list of authors.
Merged master into genFile
