Use list of numbers as a key or values

[vsraptor]

With those two convert list of nums to string to use as a key or value and back :

      # list of numbers =to=> string
	def nums2str(nums, itype='H'): #B:int8,H:int16,I:int32,Q:int64
		return struct.pack(f">{len(nums)}{itype}", *nums)

	#string =2=> tuple of numbers, use list()
	def str2nums(b, itype='H'):
		size = 1 if itype == 'B' else ('HIQ'.index(itype) + 1) * 2
		return struct.unpack(f">{len(b)//size}{itype}", bytes(b,'utf-8'))	

       index.Set(nums2str([454,7889]), nums2str([1,2,3,4]))

       m = index.Get(nums2str([454,7889])
       res = str2nums(m.GetValue())

u can add this to the docs

bytes(b,'utf-8') : assumes u got back string if u got bytestring just use 'b' directly

[vsraptor]

i still have one problem though :

always returns string even if I stored bytestring

In [314]: kv.get('abc')
Out[314]: '\x00\x01\x00\x02\x00\x03\x00\x04'

it should return b'\x00\x01\x00\x02\x00\x03\x00\x04', but does not..

I.e. there is no way to figure did u stored a list or scalar, so u can convert it back
