lua 字符串分隔，支持以单个字符或字符串进行分隔

1. local function explode ( _str, seperator)
   local pos, arr = 0, {}
   for st, sp in function() return string.find( _str, seperator, pos, true ) end do
   table.insert(arr, string.sub(_str, pos, st-1 ))
   pos = sp + 1
   end
   table.insert(arr, string.sub( _str, pos))
   return arr
   end

2. local ta2 = explode("hsee_,sdj_,ehi_,djsd","_,")
   local newSt2 = table.concat(ta2,"\n")
   print(newSt2)
