[BioC] regarding to flowCore/read.FCS warning message

[Mike]

Hi,Stevan,

This warning message is due to the fact that R doesn't handle unsigned 
integer of size larger(or equal) than 4 Bytes.
If your raw files store data as non-integer type (float or double),you 
can safely ignore this warning. Let me know if you have more questions 
regarding to flowCore.
