Temporary Data Stored Inside User's Home Directory

[DarioS]

Temporary files downloaded to the user's computer are stored in /home/userName/.ExperimentHub/folderID. Typically, user home directories on a department's server have disk quotas enforced. Perhaps this data folder should be defined by R's tempdir() command instead? Folders in /tmp/often don't have disk quotas and are automatically deleted when the time is right.

This could be addressed by exposing the ExperimentHub::ExperimentHub() extra arguments through curatedTCGAData(), which include an option to specify cache location.
