* OptionsParser now has a singleton.
* We now use the cmdline opt -p <senseApiLibPath>, and search for
the specified library in:
* senseApiLibPath, then CWD, then the place where our executable
is running from, and then finally we let the hosting OS do
its own search.
* We now call dlsym() on dlopen()'d libs to to get the senseApiDescFn
pointer.
