For some reason it won't handle certain characters...

    Input:
    Feature: 37, threshold: 4386, +
    Feature: 11, threshold: 1, +
    Feature: 10, threshold: 13, +
    Feature: 0, threshold: 34, +
    Feature: 39, threshold: 44, +

    Example:
    x[37] >= 4386

    Output:
    x[37]  4386
    x[11]  1
    x[10]  13
    x[0]  34
    x[39]  44
