Ezigrade 4.0.2.16

Following updates to the Pipe routines: (1) You can lock a pipe. This protects the pipe from being changed when you do a "set all constraints". (2) New menu item to allow you to "lock selected", "unlock selected", "lock all", "unlock all". (3) New menu item to change parameters for locked item only. Also options to only change a certain parameter. eg min grade and nothing else (4) new menu item for "set all constraints" with options to only change a certain parameter. (5) re-ordered the menu items so they are more in the order of doing things left to right (6) added in a new parameter of offset. This parameter has a maximum distance. Setting this means the lateral can finish above the main and then joined with a vertical riser. (7) when running pipes PDF report it checks first whether we need to recalculate, calc catchment areas, calculate pipe sizes etc (8) The PDF report. Sections are smarter. If they are short we put up to 3 sections across the page. (9) PDF report. Pipes displayed and plotted are in order of 1st main 1st submain laterals 2nd submain laterals 2nd main etc (10) If the pipe doesn't have a valid solution we remove the depth constraints and draw a profile anyway. In the plan view we have a purple squiggly line on this pipe to easily find it.
