Detailed Description

This is a structure for keeping track of how long the interpolation methods spend on different parts of the interpolation.

_eigenTime keeps track of how much time is spent using Eigen's linear algebra packages

_iterationTime keeps track of how much time is spent iterating over matrix indices (this is also a catch-all for time that does not obviously fit in the other categories)

_searchTime keeps track of how much time is spent on nearest neighbor searches (when applicable)

_varianceTime keeps track of how much time is spent calculating the variance of our interpolated function value (note: time spent using Eigen packages for this purpose is tallied here, not in _eigenTime)

_totalTime keeps track of how much time total is spent on interpolations

_interpolationCount keeps track of how many points have been interpolated
