The follwing methods have a discrepancy between their signature and their binding description. Ideally the const keyword should be added but I am not sure if this is allowed because it would alter the interface.

This code is used to patch the output of hdr_parser.py before ffi ruby bindings are generated from it:
<pre>
BRISK.generateKernel.parameter(0).add_flag(:IO)
BRISK.generateKernel.parameter(1).add_flag(:IO)
BRISK.operation("BRISK")[1].parameter(0).add_flag(:IO)
BRISK.operation("BRISK")[1].parameter(1).add_flag(:IO)

randShuffle.parameter(2).add_flag(:IO)
putText.parameter(0).add_flag(:IO)
chamerMatching.parameter(0).add_flag(:IO)
chamerMatching.parameter(1).add_flag(:IO)
chamerMatching.parameter(2).add_flag(:IO)
</pre>
