Addresses #8
Please merge. Spare me of the shame that was
ReplacementManager.ReplacementManagerwas a global data structure that managed a dictionary between tensors that are represented symbolically and the arrays that represent the data they contain. It was a terrible idea to have this be defined globally as this causes lots of issues when using the same symbol for different tensors.Now I simply have each tensor carry with it it's own dictionary entry to be used in the
expand_tensorfunction. The function walks through an expression tree of tensor objects and adds these entries to a dictionary local to the function. This local dictionary is used instead ofReplacementManager.
