interpolate datasets between time steps to produce a new dataset
vtkTemporalInterpolator interpolates between two time steps to produce new data for an arbitrary T. vtkTemporalInterpolator has three modes of operation. The default mode is to produce a continuous range of time values as output, which enables a filter downstream to request any value of T within the range. The second mode of operation is enabled by setting DiscreteTimeStepInterval to a non zero value. When this mode is activated, the filter will report a finite number of Time steps separated by deltaT between the original range of values. This mode is useful when a dataset of N time steps has one (or more) missing datasets for certain T values and you simply wish to smooth over the missing steps but otherwise use the original data. The third mode of operation is enabled by setting ResampleFactor to a non zero positive integer value. When this mode is activated, the filter will report a finite number of Time steps which contain the original steps, plus N new values between each original step 1/ResampleFactor time units apart. Note that if the input time steps are irregular, then using ResampleFactor will produce an irregular sequence of regular steps between each of the original irregular steps (clear enough, yes?).
Higher order interpolation schemes will require changes to the API as most calls assume only two timesteps are used.

When ResampleFactor is a non zero positive integer, each pair of input time steps will be interpolated between with the number of steps specified. For example an input of 1,2,3,4,5 and a resample factor of 10, will produce steps 0f 1.0, 1.1, 1.2.....1.9, 2.0 etc NB. Irregular input steps will produce irregular output steps. Resample factor wuill only be used if DiscreteTimeStepInterval is zero otherwise the DiscreteTimeStepInterval takes precedence
