A typo

[op-hunter]

I think it maybe a typo in file "space_l2.h" at line 225:

data_size_ = dim * sizeof(unsigned char);

why not:

data_size_ = dim * sizeof(int);

Hi @op-hunter thanks for checking the code. I think this is as it should be. The method works with single-byte integers and returns 4-byte characters. Probably calling it L2SpaceI is a bit confusing. I'll update comments to lesser the confusion.
