Adding the beginnings of a SPParks Text file Reader. This filter needs to be comprehensively tested and a test program written for it that can exercise the various options. Notably this filter does not currently figure out from the header what DataArrays will be added to the AttributeMatrix. This would be a good refactoring exercise for another programmer to perform so that DREAM3D users have a better idea of what is coming into the DataContainers. This lacking feature will notably make preflights fail for other filters as the arrays that got added will not show up in subsequent filters.
