Cannot read a ply file correctly #46

Hey, ddiakopoulos, the library is really cool. However, during my use of it, something wrong happend. I use tinyply to generate the file I needed, which contains other 4 properties for vertex. The writing part works well. When i tried to read it, it just crashed, or read some nosense content. I think the file itself has no errors, because meshlab can parse it properly. Here is the file: download_link . It's written through ascii, when i use binary format to write it, tinyply works well. However i want to figure out what happened. I will be very thankful if you will take some time to check this out!

I will take a look at this for tinyply version 2.4. As we discussed over email, the specific issue is that tinyply will write NaN values fine, but fails to read them correctly. NaNs work as expected (reading/writing) in binary mode.
