/*! \page PropertiesDoc Expectation values other than energy Keywords: AVERAGE, DENSITY and NONLOCAL_DENSITY \section description Description Three groups of operators are currently implemented.

To evaluate an operator within a given method (VMC, DMC or RMC), include the following line into that method's input section

<keyword> { <operator> <options of the selected operator> }

For simultaneous evaluation of several operators just repeat the above section for each operator to be evaluated.
