ENH: Remove unnecessary data
ENH: Move remaining testing data into Testing/Data
BUG: WriteFile was not returning an error code if an error was occuring while writing the file
BUG: PolyDataCompressionFlag test was passing even though it was not testing what it is suppose to test. Indeed, on purpose, an argument is missing. This lead to an error and the properties of the test are set to PROPERTIES WILL_FAIL true. However, the actual error was occuring because the given argument "-e ASCII" was passed instead of "-e ascii", not because of the missing flag.
BUG: * character is not expanded when run from ctest. It is only expanded when ran from the terminal. An additional test will have to be added to check that the expansion actually works.
BUG: To check that the software works when providing a file within the current working directory, we change the current working directory for the test, and only give the file name to the test instead of the whole path to the file
ENH: Addition of a test to verify that the expansion of "*" works. The test uses
 bash and is performed only on UNIX systems
ENH: Prints current file that is being saved and compressed
ENH: Prints file name of given file that is neither a vtk or a vtp file
