moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).

bugfix: inputs/VegBank/stemlocation_/create.sql: include 1 row for each stemlocation rather than for each stemcount, because stemcounts are instead imported as part of stemcount_ (which also includes taxonimportance)

inputs/VegBank/: Joined together stemcount and stemlocation tables to create stemlocation_, in order to include the stem size class's measurements in each tagged stem's stemobservation (in addition to in the stemobservation for the aggregateoccurrence as a whole)
