./install.sh and got errors.

[airglow923]

The moment I ran ./install.sh, I got:

/home/<username>/git/rexgen/src/librexgen/state/serializablestate.cpp: In member function ‘void SerializableState::addValue(const std::shared_ptr<SerializableState>&)’:
/home/<username>/git/rexgen/src/librexgen/state/serializablestate.cpp:69:3: error: ‘assert’ was not declared in this scope
   assert(childStates.find(state->getIteratorId()) == childStates.cend());

So I added #include <cassert> to rexgen/src/librexgen/state/serializablestate.cpp

Then I ran again, and I got:

/home/<username>/git/rexgen/src/librexgen/parser/RexgenFlexLexer.cpp: In constructor ‘rexgen::RexgenFlexLexer::RexgenFlexLexer(const string&)’:
/home/<username>/git/rexgen/src/librexgen/parser/RexgenFlexLexer.cpp:33:10: error: ‘memset’ is not a member of ‘std’
     std::memset(&mbs, 0, sizeof(mbs));

So I added #include <cstring> to rexgen/src/librexgen/parser/RexgenFlexLexer.cpp

I managed to install it successfully. I just want you to know about these trivial errors.
