Started adding DALEC model
initial work trying to defing write.configs.dalec
Merge branch 'master' of https://github.com/PecanProject/pecan
Revising the tree-ring code.

Converted the statistical modeling of the code from Clark et al 2007's R code into a JAGS model. Added a few small helper functions. Added a large example script that runs an analysis. Next need to refactor this code into discrete functions
added ciEnvelope function to visualization module to plot a confidence interval around an x-y plot (e.g. a timeseries)
Tree Rings

Moved JAGS code and exectution to its own function, InventoryGrowthFusion, as well as a helper function, parse.MatrixNames, which extracts the row and column info out of matrices output by JAGS
tree rings:

encapsulated the code to match the forest inventory data with the tree ring data into a single data frame

be aware, the code currently drops all trees that are not matched to rings by default. This needs to be generalized again in order to estimate plot-level statistics
Tree Rings:

defined buildJAGSdata_InventoryRings, which builds the JAGS data object for the tree ring / inventory fusion code. Also sets defaults for all the priors
Tree Cores:

Encapsulated diagnostic plots for JAGS output of tree core data
Tree Rings: misc. debugging
Merge branch 'master' of https://github.com/PecanProject/pecan
Merge pull request #69 from mdietze/master

Updates to tree ring code, start of adding DALEC model
