#' Boundary Test for the Equal Width Method
#' 
#' Tests whether a given point is contained in the bin boundary produced by the Equal Width method

#' @param point A point to be tested to see if it's inside the provided bin object
#' @param bin A bin object
#' @param inputs A list containing additional input parameters required by user supplied functions
#' 
#' @return Returns a value of TRUE if the point belongs in the bin, FALSE otherwise
