.checkSpatialDimension
                        the rows are the panel names, the columns are
                        the single cells,the column are the single
                        cells to match the SCE designs (scRNA)
.imcExperimentToPPP     map to point pattern from imcExperiment class.
cellIntensity           finds the intensities getter.
data                    data
getCoordinates          finds the spatial coords, getter.
getCoordinates<-        Sets the coordinate positions of each cell
                        (matrix), columns are X,Y positions.
getDistance<-           re-assigns the distance matrix (rows are cells)
getMorphology<-         re-assigns morphological features can be stored
                        (matrix) rows are cells and columns are Area,
                        etc.
getNeighborhood         finds the neighborhood information.
getNetwork<-            re-assigns the network assignment (matrix)
imcExperiment           Initializes a imcExperiment and performs some
                        rudimentary checks. Many of the arguments CAN
                        be NULL; determination of which is required is
                        done at run-time.  A imcExperiment must contain
                        at least the expressions and spatial/coordinate
                        assays.
imcExperiment-class     a summarized experiment of IMC runs, dimensions
                        of the spatial and intensity data are
                        regulated.#'

percentilenormalize     given a matrix of intensity counts, perform
                        min/max norm.
selectCases             subsets the imcExperiment to a case along with
                        all slots for a selected multiple ROIs.
subsetCase              subsets the imcExperiment to a case along with
                        all slots for a single ROI, using for distance
