Removed all obsolete code from the root copied classes; now everything is returned asa double (enough for plots) and as a bonus time columns are now returned as a root axis-time; as a sql server reference MSqlServer is now used and tree is a member of MSqlServer.

17// MTreeSQL //
18// //
19// A TTree object is a list of TBranch. //
20// To Create a TTree object one must: //
21// - Create the TTree header via the TTree constructor //
22// - Call the TBranch constructor for every branch. //
23// //
24// To Fill this object, use member function Fill with no parameters. //
25// The Fill function loops on all defined TBranch. //
26// //
27// MTreeSQL is the TTree implementation interfacing with an SQL //
28// database //
