Improve performance of inline functions. * NEWS.8.md: Announce compatibility and performance improvements. * scripts/legacy/@inline/inline.m: Add new field "fh" to inline class which holds an anonymous function handle implementing the inline function. Rename member variable "numArgs" to "nargs" to get away from CamelCase. * scripts/legacy/@inline/feval.m: Re-use existing class member variable "fh" to execute function rather than creating it every time feval() is called. * scripts/legacy/@inline/nargin.m: Update to use class member variable "nargs" rather than "numArgs".
