Pupose: To structure de common behavior of all measurements. It handles the timing of the measurements in a unified manner. Measurements like the compressibility or the energies are classes derived from this one. See meas_dev.H for examples. Notes: The timing comprises the following elements a) when to start the measurement (start_time) b) all long a given measurement lasts (duration) duration will be 1 unless a given measurement spans many timesteps (e.g. time corr. func.) c) sampling specifies how many times a measurement is to be made if data is to be save to a file "my_file", the name of the file must be given to the MeasuringDevice constructor (last arg). If the file name argument is missing, the data is dumped in the default log_file. Given "my_file", the data will be saved in the file "run_name.my_file.run_id" The fist line of this file is a header line that describes briefly the content of the file: # quantity_name vs. sweep_var_name quantity_name defaults to "my_file" but can be changed. sweep_var_name is determined by a call to SetUpMeasurementsOutputHeader(String sweep_var_name); IMPORTANT: YOU SHOULD NOT ASSUME THAT ANY OF THE PARAMETERS HAVE BEEN INITIALIZED WHEN CALLING THE CONSTRUCTOR YOU MUST MAKE SURE THAT THE PARAMETERS ARE SET TO THEIR PROPER VALUE BEFORE A CALL TO "Initialize()" IS MADE. This must be kept in mind when setting up arrays whose size depends on measuring times, etc...
