docs: Function: get
  
  Returns the value for the specified resource key.
  
  Example:
  To read the value for 'welomeMessage', use the following:
  (code)
  var result = mxResources.get('welcomeMessage') || '';
  (end)
  
  This would require an entry of the following form in
  one of the English language resource files:
  (code)
  welcomeMessage=Welcome to mxGraph!
  (end)
  
  The part behind the || is the string value to be used if the given
  resource is not available.
  
  Parameters:
  
  key - String that represents the key of the resource to be returned.
  params - Array of the values for the placeholders of the form {1}...{n}
  to be replaced with in the resulting string.
  defaultValue - Optional string that specifies the default return value.
