BUG: foamToEnsight replaces ":" with "_" for Lagrangian file names but retains ":" in .case file
foamToEnsight replaces ":" with "_" when writing out Lagrangian file names. However, the .case file retains the ":" when listing the filenames for ensight to read. This results in a file read error when reading into EnSight.
