Tree Ring code:  Added a Clean_Tucson function that attempts to remove duplicate tree ring records generated by WinDendro when a file is save multiple times (assumes the last one is the correct one).
Merge branch 'master' of https://github.com/PecanProject/pecan
Modifying and updating allometry code to work “offline” from PEcAn database
moved query.allom.data from db package to allometry package
Allometries: updated DESCRIPTION, data file
allom.BayesFit: updated doc, progress bar, eliminated dependency on package ‘time'
read.allom.data: created function to read and process allometry field and tally data. Ported bulk of code out of query.allom.data and now have that function call this function once it has done the database calls to find the right filepaths.
AllomAve: update documentation, created explicit output of summary stats, added call to read.allom.data if con is null, made outdir an explicit parameter rather than part of pft, added coda dependency
updated example driver code for allometries to call AllomAve and have example set up that is independent of PEcAn settings file.
