lua 字符串分隔，支持以单个字符或字符串进行分隔

1. 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)
