Honeycomb material changed to Aluminum - which is what want.
New split of reconstruction classes.   We have one `manager' class:
`AliFMDReconstructor' that contains a list of algorithms derived
from AliFMDMultAlgorithm.  Currently implemented are `AliFMDMultNaiive'
and `AliFMDMultPoisson'.
New data structure `AliFMDMult' encodes common multiplicity information.
`AliFMDMultRegion' hold multiplicity information gather from sevaral strips,
like when using the Poisson method.  This class should be extended to
give information on the average eta, phi value.
`AliFMDMultStrip' hold information on multiplicity from a single strip,
as is the case when using the naiive approach to reconstruction.
Some old and obsolete files are removed.
AliFMDMap is moved into libFMDbase as per request of Thomas Kuhr.
New subdirectory `scripts' will hold various scripts for testing, and so
on.
