Detailed Description

Ramp function base class for the set of scalar functions starting from 0 and increasing monotonically to 1 from start over the duration and remaining at 1 thereafter.

Usage:

    <entryName> <rampFunction>;
    <entryName>Coeffs
    {
        start     10;
        duration  20;
    }

or

    <entryName>
    {
        type      <rampFunction>;
        start     10;
        duration  20;
    }

Where:

Property	Description	Required	Default value
`start`	Start time	no	0
`duration`	Duration	yes
