Ezigrade 4.15

There were problems getting a valid solution for constrained grade and plane solutions joined together with hinge/hinge's.

Ezigrade 4.14

Introduced a problem with "File" -> "Save As". Field sections where being doubled up.

Ezigrade 4.13

Have added in and improved functions to create contour banks. Contour banks are added in for erosion control. It creates smaller runs for the water; thus reducing velocity.

We can now specify an alignment and hang contour banks left and right at appropriate distances or heights. These contour banks are created as drains/banks so existing drain functions can be used to edit and tweak the final design.

Access for the new banks menu item.
