Matrices

[jacobwilliams]

Add get routines for getting matrices (integer, real, etc.) from json files and objects. This could be used, for example, to easily get a variable like:

{
    "matrix": [
        [1,2,3,4],
        [1,2,3,4],
        [1,2,3,4]
    ]
}

Could also have optional inputs to indicate if the matrix is stored in column-major (Fortran-style) or row-major (C-style) order.

Would also have to check to make sure each row has the same number of columns and are all the same variable type.

Also add the corresponding set routines.

See: #212. Added a matrix_info routine to check if a variable is a valid matrix.

A corresponding set routine would be a huge plus 👍

Just checking to see if this was a dead feature request or not. The matrix_info routine works fine to check to see if a matrix exists and gets some sizes but really would love to have some get routines to read in something like this:

    "fooList":
    [
        [
            [ 0.2,0.01,0.02,0.04],
            [ 50.1,30.2,0.01,0.02,0.04],
            [ 50.1,30.2,0.01,0.02,0.04],
            [ 0.2,0.01,0.02,0.04]
        ],
        [
            [ 0.2,0.01,0.02,0.04],
            [ 50.1,30.2,0.01,0.02,0.04],
            [ 50.1,30.2,0.01,0.02,0.04],
            [ 0.2,0.01,0.02,0.04]
        ],
    ],

It's not dead... I'm just not looking forward to having to add all the wrapper for all the different variable types. :) I'll try to get to it when I can.
