 If you have some sequence URLs, like these: http://www.notchanging.com/notchanging/b1/notchanging.html
 http://www.notchanging.com/notchanging/b2/notchanging.html
 http://www.notchanging.com/notchanging/b3/notchanging.html
 ...
 http://www.notchanging.com/notchanging/b150/notchanging.html
   You needn't create a new task for each URL, just use this as
start URL: http://www.notchanging.com/notchanging/b[1-150]/notchanging.html
 When start download, PicaLoader will add the 150 URLs to
download queue as one task.   We call [1-150] "wildcard",
you can use two kind of wildcard in start URL: number wildcard and
letter wildcard. Number wildcard format: [start number-finish number] or
[0...0startnumber-finish number]. For example: [1-150] means 1,2,3....150. [001-150] means
001,002,003...150. Letter wildcard format: [start letter-finish letter]. For example:[a-Z] means a,b,c...X,Y,Z.   You can use wildcard more than one time in a start URL, for
example: Sequence URLs we want download: http://www.notchanging.com/a/001.jpg
 http://www.notchanging.com/a/002.jpg
 ...
 http://www.notchanging.com/a/150.jpg
 http://www.notchanging.com/b/001.jpg
 http://www.notchanging.com/b/002.jpg
 
...
 http://www.notchanging.com/b/150.jpg
 The start
URL should be: 
http://www.notchanging.com/[a-b]/[001-150].jpg
