Description
    Gravitational acceleration based contact angle model.
 
Usage:
    \table
        Property | Description                      | Required | Default value
        theta0   | Equilibrium contact angle        | yes      |
        gTheta   | Gravitational acceleration scale | yes      |
        thetaAdv | Limiting advancing contact angle | yes      |
        thetaRec | Limiting receding contact angle  | yes      |
    \endtable
 
    Example:
    \verbatim
    contactAngle
    {
        type           gravitational;
