 A collection of convenience handler functions for AoC 2D input arrays.
 
 - **`getCoordinateSymbol()`** - Converts a 2D `Point` point object to a string and returns its value from the 2D array
-- **`getGridDimensions()`** - Retrieves the length and width of a 2D string or number array
+- **`getGridDimensions()`** - Retrieves the length and width of a generic 2D array
 - **`isIllegalCoordinate()`** - Checks if a point at coordinate (y,x) in a grid is illegal: if it's out of bounds of the grid area or if its symbol differs from the symbol parameter.
 - **`isOutOfBounds()`** - Checks if a (y,x) coordinate is out of the grid area
 - **`getDiagonalNeighbors()`** - Retrieves the four (4) diagonally aligned (y,x) coordinates and the symbol character from a `Point` in the grid. Substitutes a `"*"` symbol character in the `PointSymbol.symbol`if the `point` is out of the grid bounds.
