Figutils adds some uibuttons at the top of any figure, which allows operation on figure data, NOT requiring source data that the figures were generated with. It's a quick way to add, subtract, or average single lines or groups of lines. You can also invert, smooth (fractional octave smoothing), or even enter an arbitrary operation involving one line, a group of lines, or one line acting on a group of lines. Data can be taken form any open figure and plotted on any open figure. Some additional functions like normalize to a specified level (at a point or using a specified freq range to average, and including linear or log based averaging), "Find most typical curve", and of course export. Coded such that additional functions could easily be added. Now added interpolation so that all curves don't have to have the same number of points like before!

Added option to interpolate if number of x axis points is not same for different curves being operated on.
fixed bug in op1 and op2 functions
fixed small bug in smoothing, added keyboard ("c") option to instantly bail out at any time.
Slight improvement in user prompts for OP! and OP2 (user defined functions) to make it clearer how to use.
