#' @name surveySmallValues
#' @rdname surveySmallValues
#' @title Report the values lower than a specified value per specified fields
#' @description This function provide a report showing all values which are lower than a certain threshold for a specified list of fields.
#'
#' @param ds dataset containing the survey (from kobo): labelled data.frame
#' @param checkperiod if not null number of day before today when the check should be made
#' @param surveyConsent name of the field in the dataset where the survey consent is stored: string
#' @param consentForValidSurvey value defined in the kobo form to acknowledge the surveyed person gave his consent: string
#' @param questionsSurveySmallValues columns name from the dataset and value you want to check against (c(col1=value1,col2=value2,...)): named list of integer
#' @param uniquerespondantID name of the field where the survey unique ID is stored: string
#' @param enumeratorID name of the field where the enumerator ID is stored: string
#' @param reportingColumns (Optional, by default it is built from the enumeratorID and the uniquerespondantID) name of the columns from the dataset you want in the result: list of string (c('col1','col2',...))
#' @param enumeratorCheck (Optional, by default set to FALSE) specify if the report has to be displayed for each enumerator or not: boolean (TRUE/FALSE)
#'
#' @return result a list that includes: 
#'   * dst      same dataset as the inputed one but with survey marked for deletion if errors are found and delete=TRUE (or NULL)
#'   * ret_log  list of the errors found (or NULL)
#'   * var      a list of value (or NULL)
#'   * graph    graphical representation of the results (or NULL)
