Usage:
after compiling this program user gets a single kernel called KF.
the following flags should be passed:
1) one of "-D BINARY_OP", "-D UNARY_OP", "-D MASK_BINARY_OP" or "-D MASK_UNARY_OP"
2) the actual operation performed, one of "-D OP_...", see below the list of operations.
2a) "-D dstDepth=<destination depth> [-D cn=<num channels]"
for some operations, like min/max/and/or/xor it's enough
2b) "-D srcDepth1=<source1 depth> -D srcDepth2=<source2 depth> -D dstDepth=<destination depth>
-D workDepth=<work depth> [-D cn=<num channels>]" - for mixed-type operations
