[LV2] Another Question

[Michael R. Fisher]

With lv2-c++-tools, the ctor and dtor of your plugin match up with 'instantiate' and 'cleanup' respectively.

I could also do the allocation in the constructor for my plugin but, since I am using lv2-c++-tools and inheriting from the plugin class, I am not sure where I can do the freeing. I hate to go with the 101 option - looks too much like my MATLAB implementation. But if it is the safest way ...
