Detailed Description

Small utility class that contains information about units.

This class can be used to contain in a single place all the information about units. Units are expressed in terms of standard PLUMED units, i.e. kj/mol, nm, and ps. Units can be set as double or as string. In the latter case, one can also use strings such as kcal/mol.
