Migrated to Github, fixed DetectionApi issue

[Sam]

Hello, new to this group..

I was attempting to use the library this morning to detect whistle sounds on a sample WAV that I provided, but it kept erroring out on my sample (I later found out because my sample rate was too low).

I needed to modify src/com/musicg/api/DetectionApi.java to verify the minimum sample rate PRIOR to actually trying to copy the data.

To make these changes, I exported the project to Github (for ease of future collaboration):

https://github.com/loisaidasam/musicg

(I also added a .gitignore file and a README with the same data from the project frontpage)

Feel free to fork and contribute..
