Class CreateContinuousFunction

Builds a continuous function from a lambda expression and a series of x values to allow a complex function to be estimated and then stacked on top of other functions to avoid the overhead in calling it gajjilions of times.

This can be a useful optimisation in probabilistic modelling where hundreds of thousands of consequences needed to be computed for each exposure. We can coalesce nearby exposures to a particular site where a hazard occurs, create a continuous function for each exposure with likely (numeric) hazard intensity values, stack the functions at each site, then call the function once at each site to compute a consequence for the entire site. In the case of a non-trivial loss function and hundreds of thousands of exposures, this can reduce computation time down dramatically.
