Define here the bond properties related with its charge distribution.

### Covalency

Covalency is a measure of the percentage ionic/covalent character of a bond. Currently no default value is provided.

### Order

Order represents the chemical bond order. Although any positive number is allowed, the usual values are 1.0 (single bond, the default), 2.0 (double bond), 3.0 (triple bond) and 1.5 (aromatic or delocalised bond).

Single, double and triple bonds are rendered in Wired mode, as single, double and triple rasterized lines. In Solid mode, single bonds are represented by a cylinder (the sigma bond), double bonds have two additional curved volumes on each side (the pi bond), and triple bonds have two more curved volumes on each side (the second pi bond).

Currently, the orientation of the curved volumes in solid secondary bonds is arbitrary. Currently, aromatic bonds are handled as normal bonds, according to its bond order, so bonds with order equal to 1.5 are handled as double bonds.
