No "im2bin" in tools. Please update readme

In examples/readme.md:

Partition the data into 8 parts.

./partition.sh train.lst ../../tools/im2bin
I dont see any im2bin nor "make" does work. How to fix this??

"~/cxxnet/tools$ make
g++ -Wall -O3 -msse3 -Wno-unknown-pragmas -funroll-loops -I../mshadow/ -I.. -DMSHADOW_USE_MKL=0 -o im2rec
g++: fatal error: no input files
compilation terminated.
make: *** [im2rec] Error 4

im2bin is not used anymore, we switch to im2rec. We will update it soon.
