HomogUniv containers now reshape incoming scattering matrices
depending upon the value of settings xs.reshapeScatter.
Number of groups is inferred from the first value added
to the object, and all incoming values are compared
against this group structure. If the number of groups for
the incoming value does not match the current group
structure, a warning messages is raised, but the value
is still stored.

If no values are presented in a line, such as
    INF_REM 0
then the branching reader will not attempt to
store this variable. A debug messages is printed

Upcoming and in-progress changes to containers.py
work only if the values passed to our container
objects are arrays, as the shape property is used
to determine/compare group structure

The HomogUniv container will now attempt to convert non-numpy
array values to arrays. This is done because the method for
determining number of groups relies upon the shape command.

Fewer warnings are printed now for variables having different
group structures. If an array comes in that should be converted
to a matrix, it's shape will be different than the current group
structure would indicate.
