Initial Release of TorQ 2.3

• Added optional write down method to wdb process, which allows data to be written to custom partition schemes during the day. At the end of day before being moved to the hdb, data is merged instead of sorted, which will allow the data to be accessed sooner. The optional method may present a significant saving in time for datasets with a low cardinality (small distinct number of elements), i.e. FX market data
• Added write access control to message handlers (using reval), which restricts the ability of querying clients to modify data in place
• Added functionality to return approximate memory size of kdb+ objects
• Bug fixes
