convert a list of matrices to an array of matrices

minimum and maximum values of vector, matrix, data frame or array

1 | ```
MinMaxObject(x)
``` |

`x` |
either a vector, matrix, data frame or array |

This helper function returns the minimum and maximum values of a vector, 2-dimensional or 3-dimensional objects. In case of a vector, matrix or data frame it returns a single value for the minimum and maximum of the object. In case of an array it returns the minimum and maximum values for each slice of the array.

# vector
x = 1:10
res = MinMaxObject(x)
# matrix
x = matrix(runif(100), 10, 10)
res = MinMaxObject(x)
# data frame
x = data.frame(matrix(runif(100), 10, 10))
res = MinMaxObject(x)
# array
x = array(runif(100), dim = c(10, 10, 3))
res = MinMaxObject(x)
