ascii animation

here's a little something i whipped up
( just a side note - ifstream file(filename.c_str()); has a problem with spaces in paths, so if you're running windows just put the text file you want animated in your C:\ directory.)

    /*
    ascii animated video program
    To create an AAV, simply create a text file with the following format
    3 <--- height of current frame
    000   \
    000    |---content of frame (doesn't matter how wide, as long as it's the same hight as specified
    000   /
    1 <--- how long the frame lasts in seconds (can be a decimal value, e.g 0.04 is 1/25th of a second

    just keep on adding sections like this to build it up frame by frame
    enjoy!
