SPOT: Sequential Parameter Optimization Toolbox

# Package Description for Roxygen:
#' Sequential Parameter Optimization Toolbox
#'
#' SPOT uses a combination statistic models and optimization algorithms 
#' for the purpose of parameter optimization. Design of Experiment methods
#' are employed to generate an initial set of candidate solutions, which
#' are evaluated with a user-provided objective function.
#' The resulting data is used to fit a model, which in turn is subject
#' to an optimization algorithm, to find the most promising candidate solution(s).
#' These are again evaluated, after which the model is updated with the new results.
#' This sequential procedure of modeling, optimization and evaluation is iterated
#' until the evaluation budget is exhausted. 
#'
#' Note, that versions >= 2.0.1 of the package are a complete rewrite of the interfaces and conventions in SPOT.
#' The rewritten SPOT package aims to improve the following issues of the older package:\cr
#' - A more modular architecture is provided, that allows the user to easily customize parts of the SPO procedure.\cr
#' - Core functions for modeling and optimization use interfaces more similar to algorithms from other packages / core-R, 
#'   hence making them easier accessible for new users. Also, these can now be more easily used separately from the main SPO 
#'   approach, e.g., only for modeling.\cr
#' - Reducing the unnecessarily large number of choices and parameters.\cr
#' - Removal of extremely rarely used / un-used features, to reduce overall complexity of the package.\cr
#' - Improving documentation and accessibility in general.\cr
#' - Speed-up of frequently used procedures.\cr
#' We appreciate feedback about any bugs or other issues with the package. 
#' Feel free to send feedback by mail to the maintainer.
