/**
* Progress Bar
* simple shortcode that displays a progress bar
* @author Chris Reynolds
* @since 0.1
* @param string $progress REQUIRED displays the actual progress bar in % or in x/y
* usage: [wppb progress=50] or [wppb progress=500/1000]
* @param string $option OPTIONAL calls various options. These can be user-input (uses CSS classes, so anything a user adds to their CSS could
* potentially be used as an option) or any of the pre-defined options/styles. Included options (as of 1.0.1): candystripes, animated-candystripes,
* red
* usage: [wppb progress=50 option="red candystripes"]
* usage: [wppb progress=50 option=animated-candystripes]
* @param string $percent OPTIONAL displays the percentage either on the bar itself, or after the progress bar, depending on which parameter is used.
* Options are 'after' and 'inside'.
* usage: [wppb progress=50 percent=after]
* @param bool $fullwidth OPTIONAL if present (really, if this is in the shortcode at all), will stretch the progress bar to 100% width
* usage: [wppb progress=50 fullwidth=true]
* @param string $color OPTIONAL sets a color for the progress bar that overrides the default color. can be used as a starting color for $gradient
* usage: [wppb progress=50 color=ff0000]
* usage: [wppb progress=50 color=ff0000 gradient=.1]
* @param string $gradient OPTIONAL @uses $color adds an end color that is the number of degrees offset from the $color parameter and uses it for a
* gradient
* $color parameter is REQUIRED for $gradient
* @uses wppb_check_pos
* usage: [wppb progress=50 color=ff0000 gradient=.1]
