function Data = getcrunch(varargin)
%GETCRUNCH- Returns the crunch values for a family (radians)
%  Crunch = getcrunch(Family, Field, DeviceList)
%  Crunch = getcrunch(Family, DeviceList)
%  Crunch = getcrunch(Family)
%
%  INPUTS
%  1. Family - Family Name 
%              Data Structure
%              Accelerator Object
%  2. Field - Accelerator Object field name ('Monitor', 'Setpoint', etc) {Default: 'Monitor' for BPM, 'Setpoint' for magnet}
%  3. DeviceList ([Sector Device #] or [element #]) {Default: whole family}
%  4. 'Physics' or 'Hardware' inputs are ignored
%  5. 'Numeric' - Numeric output {Default}
%     'Struct'  - Data structure output
%
%  OUTPUTS
%  1. Crunch - Crunch value for the family {Default: 0}
% 
%  NOTES
%  1. If Family is a cell array, then DeviceList can also be a cell arrays
%
%  See also: getgain, getroll, getfamilydata, getgolden, raw2real, real2raw
