Adds PDF export

[aamaliaa]

Adds a PDF export button and a textfield to allow the user to specify a filename.

I haven't been able to figure out how to maintain aspect ratios between each of the exports, unfortunately... I guess that's next...!

PDF Exports to a White Background, washes out lines and name details.

Any way to change export to black background?

@hweinberger - In order to change the background color prior to the PDF export, you need to add a background color immediately following the beginRecord statement. As follows:

within void draw(){
...
if(record){
beginRecord(PDF, "pdfs/"+input.getText());
background(40); // 40 is a dark background color
}

Hope that helps!
