*
* @param filename The name of the file to open

* @returns boolean true or false, depending on whether was able to open
*
* Operation:
* -# The filename will be preceeded by "file://" so move the filename
* pointer forward, past the vfs specific section of the file, and
* to the actual filename itself e.g. file://image.jpg => image.jpg
* -# Opens a filestream with read/write capabilities in binary mode
* -# Sets the handles filename
* -# Attempts to open the file
* -# If successful, calculates the length of the file
* -# returns whether the file was opened successfully
*
* @todo Add functionality to decide whether to create a new file, if the file requested does not exist
