Some problems regarding treatment of scaling factors need to be addressed

[x] when performing sums like scalarA+B, scalar A is current treated as a contraction
[x] it seems scalar * scalar is not working correctly in parallel, possibly only with sparsity
[x] the former causes issues for the python interface, e.g. C= -2*A+B does not work in parallel

These issues have been corrected by fixes in the past week to the c++ level tensor multi-contraction expression logic.
