Tidied up IDL routines
Separated out IDL routine variable reading into its own function call
Added support for GDL
Removed tab characters and trailing whitespace
Added job info flags to CFD header
Updated IDL reader for the new CFD format.

As of CFD v1.1, timestep and cycle numbers are now written into
the header block. In recent versions of EPOCH, the timestep block
is no longer written. This update ensures that such files can
still be read correctly by IDL.
Added SDF IDL reader.
Updated IDL reader to handle labels correctly.
Detect file endianness in the IDL reader.
Added Chris's IDL widget stuff.
IDL fix
Updated IDL routines for bumped SDF version number.
Updated constants with current values from NIST.
Added Chris's IDL changes

Changed logic of getdata routine. Due to problems with the use of
inherited keywords the wkdir= command has been removed and
replaced by an optional second parameter.

Syntax is now
	data=getdata(5,'Data')

Moved the data explorer to a new routine called explore_data
Syntax is
	data=explore_data('Data',snapshot=5)
First parameter is optional data directory

Quick viewer visualiser has been improved and modified.
Syntax is
	quick_view,'Data',snapshot=5
The first parameter is optional data directory

CSB
Tidied up IDL routines.
Hide all global IDL variables.

Also added "list_variables" routine and "get_wkdir" and
"set_wkdir" routines.

Usage:
    list_variables, 10, 'Data'
    wkdir = get_wkdir()
    set_wkdir, 'Data'
