v0.3.1

Significant changes

• Column plugins can now define the following functions on column definitions,
  providing more opportune timing for initialization and tear-down:
  • init, which will be executed at the time the grid's column configuration
    is (re-)applied
  • destroy, which will be executed when the grid is destroyed, as well as
    before a new column configuration is applied
• The tree plugin now supports the following column definition properties:
  • shouldExpand(row, level, previouslyExpanded), a function providing for
    conditional automatic expansion of parent rows (#141)
  • indentWidth, an integer specifying the size (in pixels) of each level's
    indent (note that the default is now 9, though it was previously 19)
  • renderExpando(), a function which can replace the default logic for
    rendering the expando node (the arrow next to the content of each cell)
• The editor plugin now augments the grid instance with an edit(cell) method
  which can be used to programmatically activate the editor in a given cell.
• A util/mouse module has been added, which exposes simulated events for
  the mouse entering and leaving grid rows and cells. (#165)
• A package.js has been added in order to streamline the build process.
  package.json has been updated to reflect the presence of package.js and
  reference the latest versions of xstyle and put-selector, each of which now
  have a package.js of their own.

Other Fixes

• Mouse events for expanding/collapsing rows in tree grids should be a bit more
  reliable. (#112)
• Rows expanded in a tree grid which has been started up but is currently hidden
  will now be rendered properly when re-shown. (#140)
• The tree and editor plugins can now both be used on the same column, by
  wrapping editor with tree. (#144)
• sortable now defaults to false for columns where field is "_item"
  or entirely unspecified (in which case there's nothing to sort by anyway).
  (#149)
• The Pagination extension now behaves appropriately with empty result sets.
  (#173)
• The ColumnHider extension now iterates over subRows rather than columns,
  making it a bit more reliable in general. (#164)
• A couple of issues with the DijitRegistry extension were identified and
  fixed. (#146, thanks jdohert)
