Summary: BicubicSpline update() doesn't work

Initial Comment:
The calculate() method in BicubicSpline is called every time the linked data matrix (zData_) changes but, due to the reserve() at line 58 of bicubicsplineinterpolation.hpp and the subesquent push_back(), every time I call update() new splines are added to the splines_ vector instead of substituting the existing ones.

My suggestion is to use resize instead of reserve, and then simply fill the allocated vector splines_.

In the attached file my proposal of change for the file bicubicsplineinterpolation.hpp, affecting only lines 58 and 60.

Best regards,

Fabio
