### Default Settings ###
eg.: You can override default control like this:
$.fn.MultiFile.options.accept = 'gif|jpg';
*/

accept: '', // accepted file extensions
max: -1, // maximum number of selectable files
maxfile: -1, // maximum size of a single file
maxsize: -1, // maximum size of entire payload
// name to use for newly created elements
namePattern: '$name', // same name by default (which creates an array)
/*master name*/ // use $name
/*master id */ // use $id
/*group count*/ // use $g
/*slave count*/ // use $i
/*other */ // use any combination of he above, eg.: $name_file$i
// previews
preview: false,
previewCss: 'max-height:100px; max-width:100px;',
// STRING: collection lets you show messages in different languages
STRING: {
remove: 'x',
denied: 'You cannot select a $ext file.\nTry again...',
file: '$file',
selected: 'File selected: $file',
duplicate: 'This file has already been selected:\n$file',
toomuch: 'The files selected exceed the maximum size permited ($size)',
toomany: 'Too many files selected (max: $max)',
toobig: '$file is too big (max $size)'

// extra file elements that are empty before execution and automatically re-enable them afterwards

### Additional Methods ###
Required functionality outside the plugin's scope
*/
// Native input reset method - because this alone doesn't always work: $(element).val('').attr('value', '')[0].value = '';
$.fn.reset = $.fn.reset || function () {
return this.each(function () {
try {
this.reset();
} catch (e) {}
});

### Default implementation ###
The plugin will attach itself to file inputs
with the class 'multi' when the page loads
*/

//$("input:file.multi").MultiFile();
$("input[type=file].multi").MultiFile();
