Feature: progress status for validation #42
Description
#Current behavior (if applicable)
when calling bag.isComplete(ignoreHiddenFiles) the system gives no feedback on where it is in the list of files to check
#Proposed behavior
When calling bag.isComplete(ignoreHiddenFiles) the system updates an object when it has completed checking a file with either success or failure.
#Why this feature is useful
This allows GUI tools to display a progress bar for the user. It would also be nice to be able to calculate and guess the time remaining but that might not be possible
#A small code example if possible
boolean ignoreHiddenFiles = true;
bag.isComplete(ignoreHiddenFiles, ProgressTrackerObject);
As far as what kind of interface the ProgressTrackerObject should have would depend on what GUI applications use (look into JavaFX and Swing)
