Adding a PFT

Plant functional types (PFTs) are used to group plants for statistical modeling and analysis. PFTs are associated with both a specific set of priors, and a the subset species for which the traits and yields data will be queried. In many cases, it is appropriate to use default PFTs (e.g. tempdecid is temperate deciduous trees)

In other cases, it is necessary to define pfts for a specific project. For example, to query a specific set of priors or subset of species, a new PFT may be defined. For example, Xiaohui Feng defined PFT's for the species found at the EBI Farm parairie. Such project-specific PFTs can be defined as `projectname`.`pft` (i.e. ebifarm.c4grass instead of c4grass).
