The long names are due to the expansion of the arguments to
CABLE_CLASS_SET and CABLE_WRAP_TCL commands in CMake.  We can get around
it by re-arranging the way we instantiate things:

CABLE_CLASS_SET(F "itk::Foo<$Float>")
CABLE_WRAP_TCL(libraryName
  "itk::Bar<$F>"
)

Produces "itkBaritkFoo_float".

CABLE_WRAP_TCL(libraryName
  "itkBarTcl:itk::Bar<itk::Foo<float> >;itkBar.h"
)

Produces "itkBarTcl".

Each reference to a CABLE_CLASS_SET using $Zot notation adds a "tag" to
the end of the name.  If we provide the tag ourselves, then that is used
for the filename.  This is similar to the difference between a nice name
using typedefs in C++ and the corresponding output in error messgaes.
