Bug Fixes & enhancements
==========================
1. Added info requested in issue #29 on generating subgrid edit url
2. Updated help info on how to generate sub grid as grid
3. Added "plugins" key to configuration to specify plugins options e.g. jqueryUI datepicker options to be used
to configure date and datetime columns as datepicker and datetimepickers respectively.
4. Renamed datepicker callback function name from dp_pikcer to synergyDataGrid.initDatePicker to avoid any possible conflicts.
5. Added logic to mark entity columns with nullable=false as required in the edit form. It appends "*" to the edit row. This can be overwritten in your column model by setting the required options
