New interface class for the compression classes.
Contains all the functions needed to do the different
steps; modelling - compressing - uncompressing - running offline etc.

Added function that writes new rootfile with digits from the
binary files. This is done in order to get the same cuts;
adc saturation, 45 degree cone etc, into the offline chain.

Added new function AliL3Modeller::CheckCluster. Function checks if the
cluster corresponding to a certain track crossing point is a good cluster;
if it is isolated and only 1 peak. If not, cluster is saved as remaining
digits.

Can print compression ratio to file in AliL3Compress::PrintCompRatio.
Minor changes to AliL3Modeller; differ between fTimeOverlap (pad)
and fTimeSearch (newly added boolean). The latter is used when searhcing
for a cluster around the track crossing point, while the first is only
used when checking for overlaps.

Added material to simulate services in front of the SPD, SDD, and SSD support
structures. Modified folumes I212, I200, and I099 so that they do not go
beyond the volume they are creating holes for. This was nessesary so that
the material added to these volumes would be correct.

Some changes resulting from last week work. The mc stuff has been removed.
Added possibility to not save the width when compressing file; this is one
by setting the flag AliL3Compress::fWriteShape.
The status of the code is that it seems to be more or less working. The
efficiency drops a little bit when running it through offline, but this
is mainly because overlapping clusters are not deconvoluted, and 2 clusters
found by the offline cluster finder will be 1 cluster after compressing/
decompressing. The only way to get rid of this, is to include some
deconvolution in the AliL3Modeller::FindClusters.

Perform check on cos(crossing_angle_with_padrow) in GetCrossingAngle().
Every once in a while this number is equal to one, which results in
return value being NaN.

Serious bugfix in Local2Raw function. This function failed to transform
corretly on the z<0 side of the tpc, because of a "wrongly" check. I have
no idea why I did not see this bug before, but probably because the
function is seldom used.

Added new function AliL3Hough::MergeEtaSlices which merges tracks which
appear in 2 neighbouring eta slices. The tracks are matching if they have
identical kappa and psi; they appear in the same bin. The one with the
lower threshold are removed from the track array.
There is also a bugfix in AliL3HoughTransformer::GetEta, the sign should
not be swicthed on the other half of TPC, because the sign is already included
in the (GetEtaMax() - GetEtaMin()).
Also the DoMC flag in the AliL3HoughTransformer ctor.
