feat($Zhuang09-OpenMP): New inspector working (for sum)

Goes with the file inspector-executor-openmp.cpp
Need to do more testing.
Tested with only one thread.
Several new commands in PseudoC (all used for debug):
        - PrintVar "varname" : Print the variable
        - PrintArray "arrayName" (VRead "size") : Print the entire array.
        - Inline "string" : to inline C code directly.
        - Comment "string" : to insert comment in the C code.

A lot of debug information is printed right now (put the debug flag in the openmp inspector to false).
