%ValveData - Data object to hold the all processing information for valve data
%ValveData inherits from AncillaryData
%
% Syntax:  valvedata = ValveData(nameIn, dataValuesIn, timestampsIn, unitsIn)
% Inputs:
%    nameIn - Description
%    dataValuesIn - Description
%    timestampsIn - Description
%    unitsIn -
%
%
% Example:
%     vd = ValveData('Valve1', ValveState, fullDate, obj.ValveUnits);
%
% Other m-files required: AncillaryData
% Subfunctions: none
% MAT-files required: none
%
% See also: AncillaryData, FlowFileLoader
