Shared keywords for all components

The following options can be used for any of the above colvar components in order to obtain a polynomial combination or any user-supplied function provided by scriptedFunction.

• name $\langle\,$ Name of this component$\,\rangle$
  Context: any component
  Acceptable values: string
  Default value: type of component + numeric id
  Description: The name is an unique case-sensitive string which allows the Colvars module to identify this component. This is useful, for example, when combining multiple components via a scriptedFunction.

• scalable $\langle\,$ Attempt to calculate this component in parallel?$\,\rangle$
  Context: any component
  Acceptable values: boolean
  Default value: on, if available
  Description: If set to on (default), the Colvars module will attempt to calculate this component in parallel to reduce overhead. Whether this option is available depends on the type of component: currently supported are distance, distanceZ, distanceXY, distanceVec, distanceDir, angle and dihedral. This flag influences computational cost, but does not affect numerical results: therefore, it should only be turned off for debugging or testing purposes.
