    It takes a testCase_components object and a ComponentData object,
    and returns a list of strings, each of which can be fed as an argument
    to eval to generate a component.

    The input function, the 'compString evalString creator', is of the form:

    It takes a testCase_components object and a component string, such as
       'myCube.vtx[1]'

    component.

    melOrPymel determines whether mel-style or pymel-style syntax will be used.
    (in general, pymel-style indices are similar to mel-style, but can allow
    things such as [:-1].  Also, different component names may be used - for
    instance, the mel-syntax 'myNurbsSphere.v' will result in a v-isoparm,
    whereas PyNode('myNurbsSphere').v will give you the visibility attribute,
    so PyNode('myNurbsSphere').vIsoparm must be used. )

    case, only compData which have associated index data (of the correct mel-or-
    pymel syntax type) will generate evalStrings.

    If indexed is False, then returned components will not have an index.
    In this case, alwaysMakeUnindexed will control whether given compData
    objects generate an evalString - if alwaysMakeUnindexed, all compData will
    be used, whereas as if it is false, only compData which have no index data
