struct State the main type for states of input variables (particles). This type is intended only for storing of information but no arithmetic should be performed on it. For the latter, we have the DState.

struct VState: A State-like variable but acting like a vector with arithmetic operations defined on it, while State acts more like a Point i.e. a fixed object that cannot be manipulated. The main application of VState is as a derivative of a State; see also Vstate_type, ...

Find the indices of continuous properties, and return the indices as well as the symbols and types

Generate an atom with the given properties.

change how many digits are printed in the PState or VState output

convert a PState to a corresponding VState (basically just remove the discrete variables)
