Generates a density grid with or without a priori defined limits

Generates a density grid that can then be used for heatmap or countour plots.

densityGridDS(
  xvect,
  yvect,
  limits = FALSE,
  x.min = NULL,
  x.max = NULL,
  y.min = NULL,
  y.max = NULL,
  numints = 20
)

`xvect`	a numerical vector
`yvect`	a numerical vector
`limits`	a logical expression for whether or not limits of the density grid are defined by a user. If `limits` is set to "FALSE", min and max of xvect and yvect are used as a range. If `limits` is set to "TRUE", limits defined by x.min, x.max, y.min and y.max are used.
`x.min`	a minimum value for the x axis of the grid density object, if needed
`x.max`	a maximum value for the x axis of the grid density object, if needed
`y.min`	a minimum value for the y axis of the grid density object, if needed
`y.max`	a maximum value for the y axis of the grid density object, if needed
`numints`	a number of intervals for the grid density object, by default is 20

Invalid cells (cells with count < to the set filter value for the minimum allowed counts in table cells) are turn to 0.
