    Returns a list of differences in one schema to the other

    Returns a list of differences in one schema to the other

    schema1

    The first schema to compare

    schema2

    The second schema to compare

    parent

    Parent path. Should be left default by the users first run. This is used for the accumulation of differences and their print out.

    The first schema to compare

    schema2

    The second schema to compare
