v1.3.3

Changes in this release:
-- Bug fixed where if the Scenario named contained square brackets, a warning was thrown
-- External files are no longer copied by default during multiprocessing runs (can set this using the "copyExternalFiles" argument in the run() function)
-- New "filterColumn" argument in datasheet() and datasheetRaster() functions that allow the user to filter a datasheet or raster file by a column value
