Bioswale Fix

2015/10/20 Version 4.2.10 addresses 2 issues described below.  Both issues are considered programing bugs.  According to the version numbering system in use as of October 21, 2015, the digits after the last decimal point are changed for this WWHM update.
(1)- Fixed a bug that occurs when using the arched pipe option in the tank element.  The bug occurs in the last line of the stage-area-storage-discharge table.  Because the area at the top of an arched pipe is 0 the incremental storage = 0 and this caused an incorrect storage value for this line.  If the arched pipe never gets completely full then this will not impact the user.  However, if the pipe does get completely full you will get an error.  This issue has been resolvedby making the incremental storage an extremely small (0.001 x value of prior stage)non-zero value ?
(2)- Fixed a bug that occurs in the SSD Tableelement with multiple layers. The SSD table would not refresh after the user pressed on the “Add Layer” button and added another layer.  This bug likely resulted in SSD tables with multiple layers generating an incorrect FTABLE and incorrect results.  This issue has been resolved by ensuring the table refreshed after the user added a layer with the “Add Layer” button. .

Added new commercial element

2015/06/03 ALL  *** IMPORTANT UPDATE ***

An adjustment to the coefficient of discharge has been made that alters this value from 0.60 to 0.62. This results in a 3% increase in the discharge of the orifice.  All existing models can be modified by a small adjustment to the orifice size to produce the same results.  

The flow through the riser equation has been adjusted to account for a head condition above the riser greater than the riser radius.  This adjustment transitions the discharge from the weir equation to the orifice equation.  This adjustment will have little impact to most model results but can impact designs where there are significant head values on the riser.

The vertical orifice option for the Bioswale element was incorrectly applying precipitation to the element.  This will impact only bioswale elements using the vertical orifice option.
